True Christians are disciples of Jesus.
Explanation Required: The born again, Jesus, and the unsaved; a pictorial.
Everyone born again receives the Spirit of God; first by the Word through belief, and second by the Holy Ghost through repentance from the deeds of the flesh. We need both to be saved. Then, by the Spirit of God we strive to live "inside-out" like Jesus did, doing the will of the Father (the soul of God) including the works and miracles Jesus did.
This image depicts Jesus before His death and resurrection. Note, the Word of God IS His spirit of man, and the Holy Ghost dwells in Him as it does all of the born-again believers in order to be raised from the dead when our body dies. Jesus lived "inside-out".
This image represents the unsaved person destined for hell. The unsaved live "outside-in" by the will of their flesh and the friendship of the world.
- ...know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God. James 4:4.
