When Jesus said, “And whatsoever ye shall ask in my name, that will I do,” He wasn’t talking about prayer. The word “ask” is the Greek “aiteō” and it’s a substitute for the word “require.” It’s different from what we have in John 16:23 where Jesus said, “And in that day ye shall ask me nothing. Verily, verily, I say unto you, Whatsoever ye shall ask the Father in my name, he will give it you.”
In the case of the latter, the word “ask” is “erōtaō” (Greek), which is prayer. Here, Jesus was showing us how to pray to the Father in His Name. But the “ask” in our theme verse is talking about you making a demand in the Name of Jesus.
In Acts 3:1-6, the Bible shows us how Peter and John put this to work. They encountered a man crippled from birth who daily begged for alms at the temple gate. Peter said to him, “...Silver and gold have I none; but such as I have give I thee: In the name of Jesus Christ of Nazareth rise up and walk” (Acts 3:6). This isn’t prayer; Peter made a demand in the Name of Jesus.
Prayer
In the Name of Jesus, I come against the demons of darkness, the demons of deception, confusion and chaos; spirits of violence causing destructions in the nations of the world; I paralyse their efforts! I declare that these demons of violence will not prevail. I break the influence and dominion of Satan over the nations and their leaders, in the mighty Name of Jesus. Amen!
