When He is in you and you are in Him, you are one with Him.   

When you are one with Him, you can do all things by Him.   

How is this oneness possible as Jesus has a body?   
It is by absorbing His Word and being absorbed by His Holy Spirit.   

And now I am no more in the world, but these are in the world, and I come to you.     Holy Spirit Father, keep through your power those whom you have given me, that they may be one, as we are. Joh 17:11 In Spirit Baptism we are One with Him.      Those who reject the infilling Holy Spirit are rejecting Christ Jesus who is His express image.      To love Jesus and despise His Holy Spirit is like loving a woman for her body and caring nothing for her spirit and soul.     Unlike a woman, our Lord cannot be so deceived.     Neither is He interested in such a relationship.
