John 1:12-13 (NIV)

¹² Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God— ¹³ children born not of natural descent, nor of human decision or a husband’s will, but born of God.

Romans 8:15 (NIV)

¹⁵ The Spirit you received does not make you slaves, so that you live in fear again;rather, the Spirit you received brought about your adoption to sonship.^[a] And by him we cry, “Abba,^[b] Father.”
