Well the only "True" christian I know "for sure" is Jesus Christ....but my wife and Chuck Poole have displayed this characteristic more than any person i have met in this lifetime. I only call myself a believer because it would be VERY presumptuous to include myself, as a Christian. I relate more with Saint Paul- The Chief of All Sinners. THE ONLY THING I KNOW , FOR SURE, IS THAT JESUS WAS A CHRISTIAN.
1Jn 5:13 These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
A very good answer.
(BTW...it didn't come from Paul )
