He who is of God (belong to God) hears God’s words; therefore (for this reason) you do not hear, because you are not of God (John 8:47). Can you be a Christian and not follow Christ? The answer is NO.
The proof that you are really a Christian is that you follow Christ. The way you follow Christ is through the words of God (the Bible, the scriptures). You do not make excuses, you do not challenge and say it is not Gods word but you believe by faith, follow by faith and watch God give you the revelation of the word being true.
You will behold this truth for yourself and it will not be because someone told you but because God revealed the truth of JESUS CHRIST which is the truth of His word to you.
Follow Christ to be a true Christian (a true believer).
