"Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son" (2 Jn. 1:9 AV).
Beyond question, the doctrine of The Christ is founded upon the bedrock that Jesus is God incarnated in human flesh, being both fully God and fully man, inseparably united in one, never separated from His attributes as The God.
To claim and believe that Jesus was not omnipotent during HGis earthly ministry means, according to the above verse, that the person has neither the doctrine of Christ nor The God of the Bible.
That should cause one to pause for a moment of self-examination, eh?
He was not “walking in” His omnipotence while on earth.
Does that clear it up?
The reason this is important to understand how Christ was fully God, but did not walk in Him omnipotence while on earth, is so that we can understand the nature of what He accomplished here on earth.
There is a tendency to say to oneself, “Oh, Jesus was God, so remaining sinless, doing the miracles, fasting for forty days in the desert, hanging on the cross for three days, being scourged and crowned was not a big deal. He was God, so it felt different for Him than it would for us.”
Wrong. My point is that Christ’s deity can not detract from His humanity. His suffering was real. His ordeals on earth were not mitigated by His divine nature. He literally sweated blood in the Garden... as a man. (there is scientific basis for sweating blood, btw).
It’s important to remember the truth that He was tempted as we are in all things, and yet overcame that temptation in His nature as a Man...NOT because He was God and therefore it was easier for Him to do so.
Ultimately this can give the spirit-filled Christian encouragement, to remember He could overcome what we are facing in our daily lives, so therefore we can, too!
