When does life as a Christian begin?

Answer 1

When you accept Christ into your heart.

The New Testament perspective:2 Corinthians 5:17 - Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.

According to Paul, a new life begins when one is placed "in Christ." How and when does this happen?

Romans 6:3, 4 - Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.

Colossians 2:11, 12 - In Him you were also circumcised with the circumcision made without hands, by putting off the body of the sins of the flesh, by the circumcision of Christ, buried with Him in baptism, in which you also were raised with Him through faith in the working of God, who raised Him from the dead.
