5 Bible Verses about Adoption, Assurance Of

The Spirit Himself testifieth with our spirit, that we are children of God;

For as many as are led by the Spirit of God, these are sons of God.

For ye did not receive a spirit of bondage again unto fear; but ye received a spirit of adoption, whereby we cry, "Abba, Father."

Whosoever has been begotten of God sins not; because His seed abides in him, and he cannot sin because he has been begotten of God. In this are manifest the children of God and the children of the Devil: every one that does not righteousness is not of God, neither he that does not love his brother; because this is the message which ye heard from the beginning, that we should love one another;read more.
not as Cain who was of the evil one, and slew his brother. And wherefore did he slay him? Because his own works were evil, and his brother's righteous. Marvel not, brethren, if the world hates you. We know that we have passed out of death into life, because we love the brethren. He that loves not abides in death. Every one that hates his brother is a murderer; and ye know that no murderer has eternal life abiding in him. In this we have known the love, that He laid down His soul in our behalf; and we ought to lay down our souls in behalf of the brethren. But whosoever possesses the goods of the world, and beholds his brother having need, and shuts up his compassion from him, how does the love of God abide in him?

and ye have forgotten the exhortation which, indeed, reasons with you as with sons: "My son, do not lightly regard the chastening of the Lord; neither faint, when reproved by Him; for whom the Lord loveth, He chasteneth, and scourgeth every son whom He acknowledgeth." For chastening endure ye: God dealeth with you as with sons; for what son is there whom his father chastens not?read more.
But, if ye are without chastisement, of which all have become partakers, then are ye bastards, and not sons. Furthermore, we used to have the fathers of our flesh as chasteners, and we reverenced them: shall we not much rather be in subjection to the Father of our spirits, and live? For they, indeed, for a few days were chastening us, according to what seemed good to them; but He for our profit, that we may partake of His holiness. All chastening, indeed, for the present seems not to be joyous, but grievous; but afterward it yields the peaceful fruit of righteousness to those who have been trained thereby.
