WHY IS THE NAME OF JESUS ALL POWERFUL?

And I will do whatever you ask in My Name (as My representative), this I will do, so that The Father may be glorified and celebrated in The Son. If you ask Me anything in My Name (as My representative), I will do it.
John 14:13-14 (AMP)

I pray that you will begin to understand how incredibly great His Power is to help those who believe Him. It is that same Mighty Power that raised Christ from the dead and seated Him in the place of honor at God’s Right Hand in heaven, far above any other king or ruler or dictator or leader. Yes, His Honor is far more glorious than that of anyone else either in this world or in the world to come. And God has put all thing under His Feet and made Him the Supreme Head of The Church.
Ephesians 1:19-22 (TLB)

The seventy came back full of joy. They said, “Lord, even the demons obeyed us when we used Your name.”
Luke 10:17 (NLV)
