How should I pray, in order to win a spiritual battle?

"Lord, if it is Your will, please help her..."

Wait a minute, don't you know His will? It is written in His Word!

"God, use Your almighty power to help her..."

Hold a second, hasn't God already given us His authority? Jesus is the head and we are the body which carries out the work, and God is not going to use His almighty power where He expects us to use it.

So let's try again:

"Father, Your Word says..."

"And in the name of Jesus, we declare..."

Amen!
