And, what do these definitions tell us? First of all, they reveal that the term is self-applied; that is, all one has to do is say he believes, and poof, he is a Christian. I do not find that consistent with the Scriptures. A genuine believer in Jesus Christ must be born again (Jn. 3:3-8). A genuine believer in Jesus Christ actually believes in Him with all his heart, and he publicly confesses Jesus to be his Lord (Mt. 10:32; Acts 8:37; Rom. 10:9-10; 1 Jn. 4:2-3; etc.). A genuine believer will declare his faith in Jesus, publicly, by being baptized (Acts 2:41; 8:12; 8:36-38; 9:18; 10:47-48; 16:30-33; 18:8; 22:16; etc.). And a genuine believer will strive to live according to the teachings of his Lord and Savior, Jesus Christ (Jn. 10:4; 10:27; 12:26; 21:19-22; etc.). A genuine believer is a member of God's family, not a religion (Mt. 5:9; Lk. 20:36; Jn. 1:11-12; 11:52; Rom. 8:16; Gal. 3:26; 1 Jn. 3:10; etc.)! We are His adopted children, His family, not a religion (Rom. 8:15; Gal. 4:5; Eph. 1:5; etc.)!
The word "Christian" is from the Greek Χριστιανός (Christianos), which occurs three times in the Bible (Acts 11:26; 26:28; 1 Pet. 4:16). What can be learned from these verses is: non-Christians labeled Christ's followers as Christians (Acts 11:26). Being a Christian meant one must be converted from believing in someone or something other than Jesus (Acts 26:28). And, if you were to allow yourself to be identified as a believer and follower of Jesus, there was a good possibility that you would be persecuted (1 Pet. 4:16). That is still true in many parts of the world, and is becoming true more and more today in America! So hang on; we will soon find out who is professing to be a believer, and who actually is one!
I am not a member of a religion; I am a child of God by faith in Christ!
