“in the Name of Jesus” is not just a tagline to put at the end of a prayer.
Think of asking “according to His will” in the Nature, character, and Authority of His Royal Name.
I like to think of it from the perspective of being adopted into the Royal family and the authority that comes with the royal robe and signet ring.
Here are a few verses to ponder.
Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Matthew 7:22-23 (KJV)
Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth.
And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so.
And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye?
And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded.
Acts 19:13-16 (KJV)

For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
For as many as are led by the Spirit of God, they are the sons of God.
For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
The Spirit itself beareth witness with our spirit, that we are the children of God:
And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
Romans 8:13-17 (KJV)
