I just bought a book by Joyce Meyer called, "The Secret Power of Speaking God's Word." It has already been a great help to me. Joyce says that by speaking God's words aloud we are strengthened and the evil angels must leave us.
The Bible verses are listed by topic such as: Courage, Depression, Forgiveness, Peace, etc. She also writes each verse as though you yourself are speaking it.
As an example:
"I am gentle and forbearing with others and if someone has a complaint against me, I readily pardon him; even as the Lord has freely forgiven me, so must I also forgive." Colossians 3:13
"He heals my broken heart and binds up all my wounds." Psalm 147:3
"I'm sticking with God. I say it over and over again - He is all I have left. He proves to be good to me and to all who passionately wait and diligently seek him. It's a good thing to quietly hope for help from God."
Lamentations 3:24-26
