A person becomes connected to Jesus by faith through baptism and experiences a “circumcision of the heart,”, which creates inner renewal. By God placing his being into the person through the Holy Spirit, the person becomes – spiritually – reborn.
Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.
Romans 6, 3-6
Colossians 2, 11-13
for all of you who were baptised into Christ have clothed yourselves with Christ.
I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh.
Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God—children born not of natural descent, nor of human decision or a husband’s will, but born of God.
2 Corinthians 5,17
Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!
He saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit.
1 Peter 1,23
For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God.
