It is not possible to be "born a Christian" or "saved since birth", "born saved", "born a born again Christian" etc.
All are born in sin. You must acknowledge your a sinner
for all have sinned and fall short of the glory of God
You must confess that Jesus Christ is your Savior, GOD Himself.
That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved.
Jesus said it Himself that you must be born again in order to enter the Kingdom of Heaven.
3In reply Jesus declared, "I tell you the truth, no one can see the kingdom of God unless he is born again."
4"How can a man be born when he is old?" Nicodemus asked. "Surely he cannot enter a second time into his mother's womb to be born!"
5Jesus answered, "I tell you the truth, no one can enter the kingdom of God unless he is born of water and the Spirit. 6Flesh gives birth to flesh, but the Spirit gives birth to spirit. 7You should not be surprised at my saying, 'You must be born again.'
