What is a real Christian?
A Christian is someone who has decided to entrust his or her life to Jesus Christ. A Christian trusts Christ for forgiveness of sin, a right standing before God, and guidance in life.
Christian's are sometimes referred to as "born again" because Jesus said that one must be born of the water (the physical birth) and the Spirit:
"Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God." 4 Nicodemus said to Him, "How can a man be born when he is old? He cannot enter a second time into his mother's womb and be born, can he?" 5 Jesus answered, "Truly, truly, I say to you, unless one is born of water and the Spirit he cannot enter into the kingdom of God. 6 "That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. 7 "Do not be amazed that I said to you, 'You must be born again.'
To be born again--born of the Spirit--a person must place his or her trust in Jesus Christ (See How does one become a Christian?. The Spirit of Jesus Christ actually comes to dwell within the new Christian, giving newness of life--His life.
