Romans 3:22-30 (23)

 ²²Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: ²³For all have sinned, and come short of the glory of God; ²⁴Being justified freely by his grace through the redemption that is in Christ Jesus: ²⁵Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; ²⁶To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. ²⁷Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith. ²⁸Therefore we conclude that a man is justified by faith without the deeds of the law. ²⁹Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also: ³⁰Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith. ³¹Do we then make void the law through faith? God forbid: yea, we establish the law.

Romans 6:22-23 (23)

 ²²But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life. ²³For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

John 1:5-14 (120

 ⁵And the light shineth in darkness; and the darkness comprehended it not. ⁶There was a man sent from God, whose name was John. ⁷The same came for a witness, to bear witness of the Light, that all men through him might believe. ⁸He was not that Light, but was sent to bear witness of that Light. ⁹That was the true Light, which lighteth every man that cometh into the world. ¹⁰He was in the world, and the world was made by him, and the world knew him not. ¹¹He came unto his own, and his own received him not. ¹²But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: ¹³Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. ¹⁴And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.

Revelation 3:17-22 (20)

 ¹⁷Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked: ¹⁸I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see. ¹⁹As many as I love, I rebuke and chasten: be zealous therefore,
and repent. ²⁰Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me. ²¹To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne. ²²He that hath an ear, let him hear what the Spirit saith unto the churches.

Acts 16:25 - 34

²⁵And at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard them. ²⁶And suddenly there was a great earthquake, so that the foundations of the prison were shaken: and immediately all the doors were opened, and every one’s bands were loosed. ²⁷And the keeper of the prison awaking out of his sleep, and seeing the prison doors open, he drew out his sword, and would have killed himself, supposing that the prisoners had been fled. ²⁸But Paul cried with a loud voice, saying, Do thyself no harm: for we are all here. ²⁹Then he called for a light, and sprang in, and came trembling, and fell down before Paul and Silas, ³⁰And brought them out, and said, Sirs, what must I do to be saved? ³¹And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. ³²And they spake unto him the word of the Lord, and to all that were in his house. ³³And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway. ³⁴And when he had brought them into his house, he set meat before them, and rejoiced, believing in God with all his house.

John 3:14-21 (15,16)

 ¹⁴And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: ¹⁵That whosoever believeth in him should not perish, but have eternal life. ¹⁶For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. ¹⁷For God sent not his Son into the world to condemn the world; but that the world through him might be saved. ¹⁸He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. ¹⁹And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. ²⁰For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. ²¹But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.

John 3:35,36

³⁵The Father loveth the Son, and hath given all things into his hand. ³⁶He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.

John 4:37-40,

³⁷All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. ³⁸For I came down from heaven, not to do mine own will, but the will of him that sent me. ³⁹And this is the Father’s will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. ⁴⁰And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.

John 4:42-48 (47)

  ⁴²And they said, Is not this Jesus, the son of Joseph, whose father and mother we know? how is it then that he saith, I came down from heaven? ⁴³Jesus therefore answered and said unto them, Murmur not among yourselves. ⁴⁴No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day. ⁴⁵It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me. ⁴⁶Not that any man hath seen the Father, save he which is of God, he hath seen the Father. ⁴⁷Verily, verily, I say unto you, He that believeth on me hath everlasting life. ⁴⁸I am that bread of life.

 1 John 5:1-13 (10)

¹Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him. ²By this we know that we love the children of God, when we love God, and keep his commandments. ³For this is the love of God, that we keep his commandments: and his commandments are not grievous. ⁴For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith. ⁵Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?

⁶This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth. ⁷For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. ⁸And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one. ⁹If we receive the witness of men, the witness of God is greater: for this is
the witness of God which he hath testified of his Son.

¹⁰He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son. ¹¹And this is the record, that God hath given to us eternal life, and this life is in his Son. ¹²He that hath the Son hath life; and he that hath not the Son of God hath not life. ¹³These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.

Acts 4:10-13

¹⁰Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole. ¹¹This is the stone which was set at nought of you builders, which is become the head of the corner. ¹²Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved. ¹³Now when they saw the boldness of Peter and John, and perceived that they were unlearned and ignorant men, they marvelled; and they took knowledge of them, that they had been with Jesus.

1 John 4:7-16

 ⁷Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God. ⁸He that loveth not knoweth not God; for God is love. ⁹In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him. ¹⁰Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins. ¹¹Beloved, if God so loved us, we ought also to love one another. ¹²No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us. ¹³Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit.

 ¹⁴And we have seen and do testify that the Father sent the Son to be the Saviour of the world. ¹⁵Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God. ¹⁶And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him.

1 Timothty 1:15

 ¹⁴And the grace of our Lord was exceeding abundant with faith and love which is in Christ Jesus. ¹⁵This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.

Titus 3:1-10 (4,5)

¹Put them in mind to be subject to principalities and powers, to obey magistrates, to be ready to every good work, ²To speak evil of no man, to be no brawlers, but gentle, showing all meekness unto all men. ³For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another. ⁴But after that the kindness and love of God our Saviour toward man appeared, ⁵Not by
works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost; ⁶Which he shed on us abundantly through Jesus Christ our Saviour; ⁷That being justified by his grace, we should be made heirs according to the hope of eternal life. ⁸This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men.

⁹But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain. ¹⁰A man that is an heretic after the first and second admonition reject; ¹¹Knowing that he that is such is subverted, and sinneth, being condemned of himself.

Revelations 22:12-20

 ¹²And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be. ¹³I am Alpha and Omega, the beginning and the end, the first and the last. ¹⁴Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city. ¹⁵For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie. ¹⁶I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star. ¹⁷And the Spirit and the bride say, Come.  And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely. ¹⁸For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: ¹⁹And if any man shall take away from the words of the book of this
prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.

²⁰He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus. ²¹The grace of our Lord Jesus Christ be with you all. Amen
