1 John 2:29

[29] If you know that he is righteous, you may be sure that everyone who practices righteousness has been born of him. (ESV)

1 John 3:1–3

[1] See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him. [2] Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is. [3] And everyone who thus hopes in him purifies himself as he is pure. (ESV)
