because what is called christian today is not what it is in scripture. Today it means a "church" member. But it was originally a name for disciples of Christ. A disciple of Christ says and does ALL Christ says to do because he believes Jesus is God's leader. Church christians do what the man/men leading them believes so there are very few true disciples of Christ because the people have been taught to follow these apostate men. ask the average church member what their religion is they will say i am a baptist or lutheran or the name of their particular "church"
Jesus says if your love for me is not so much greater than that for ANYTHING OR ANYONE else that your love for the other looks more like hate, then YOU CANNOT BE MY DISCIPLE. The "church" system has destroyed what was Christianity and turned it into christianity, a work of man with out the influence of God.
Only those that have cast aside the teachings of men and have learned TRUTH from the Holy Spirit of God who was sent to bring us All truth and follow Christ the Son of God, who is the Lord of this final age of man, have remained true to His description of what a disciple of Christ must be. Wake up people, repent, be born again. be baptizes in water, in the Holy Spirit, and follow Him only as led by the Holy Spirit.
John 3:5-8 Jesus answered, "Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter 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 marvel that I said to you, 'You must be born again.'
