Back to the basics, what is a Christian?

All of this time spent during the past week defending the modern Biblical text against KJV Only advocates was necessary, but unfortunate when so much work is needed for the kingdom of God.  With that in mind, let me return to a topic that has been close to my heart for years and about which I wrote a book several years ago:  What defines a Christian?  How do we know if someone is a Christian or not?  The source for these thoughts is exclusively the first letter of the Apostle John, one of my favorite portions of Scripture, during which he repeatedly states this three-pronged thesis in a variety of ways.  The three part standard of John is reflected in fifty-two statements in his letter that will confirm or deny that someone is a genuine follower of Jesus Christ.  Those fifty-two statements are easily placed into three categories: (1) Belief, primarily that Jesus is the Christ the Son of God, (2) Love, primarily for fellow Christian brothers and sisters, and (3) Obedience, focused on keeping the commandments of God.
In his letter, John makes 17 statements about belief, 14 statements about love, and 19 statements about obedience.  All three are necessary, to be a Christian, one MUST believe in Christ, one MUST love other Christians, and one MUST become obedient to the commands of God.  None of this is optional, none of this can be excused in the name of some other cause.  In other words, to defend Christ by showing hatred to other Christians cannot be the proper path.  Likewise, compromising any one of the three will endanger our ability to have any real confidence in our own salvation.

For a full examination of this issue, as well as an attempted application of it regarding various groups that hang around the fringes of Christianity like the Jehovah's Witnesses or the Mormons, please read my book.  And yes, I know the introduction needs to be updated to reflect my work here in PA and our newly arrived bundle of joy; I'll get to that at some point.
