16 We know love by this, that He laid down His life for us; and we ought to lay down our lives for the brethren. 1 John 3:16 (NASB)
What differentiates a genuine Christian from one whose religion is only skin-deep? Jesus said that He knows those who are His. He calls them His sheep who hear His voice and follow Him. (John 10:27) He also called them His disciples. He gave us the requirements for being His disciple in Matthew 16:24, Mark 8:34 and Luke 9:23 where he said that if anyone desires to follow Him they must deny themselves, take up their crosses and follow Him. If we combine these two views then we learn that our Lord’s sheep, His disciples, are those who hear His voice, deny themselves, take up their crosses and follow Him. This is telling us that genuine Christians are those who humble themselves before their Lord, die to self, submit to Him as Lord, obey Him, and emulate Him as He leads.
