O Really wrote: "My understanding is that one becomes a Christian by "accepting Jesus Christ." At least that's what Billy Graham said for years. I haven't looked it up, but I think there is also some references in the Bible that one is saved by belief, not by acts. Further, I seem to recall reading that only God is perfect, and that everyone else sins. So it seems kinda hard to say that a sinner who is a believer (or a believer who is a sinner) isn't a "true" Christian."
Romans 10:9-16 (KJV)
9. That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10.
** For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
11. For the scripture saith, Whosoever believeth on him shall not be ashamed.
12. For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
13. For whosoever shall call upon the name of the Lord shall be saved.
** Once one has accepted (truly accepted) in his/her heart, knowledge and belief in Jesus Christ, the believing Christian should strive to turn away from
the evils and temptations of the world. "For all have sinned and come short of the glory of God." By professing a belief in God and yet continuing to live a life of deceit, hatefulness, and malice towards others is definitely not that of a Christian, regardless of what you say you are.
The devil also believes in God, that does not make him a good person or a Christian.
