For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. (Rom. 10:10)
Something that hinders many people is that they mentally try to believe they receive. They are just imitating someone else.
With their mind, they say, "Yes, I believe."
You can usually tell when people are talking out of their mind or when they are talking out of their spirit. You see, your heart is your spirit, and your spirit is your heart.
With the heart, man believeth. There will be a lack of conviction - a lack of assurance - when a person is speaking out of his or her mind. There will be hesitancy.
When I lay hands on people to be healed, I sometimes say to them, "Will you be healed now when I lay hands on you?"
Some people say, "Well, uh, yes, I believe." But I know they're not in faith.
I've had other people say, "I sure will! Just lay your hands on me and watch it! I'll be healed right now!" That's assurance. You can tell that right away. When I lay hands on them, it's like I am holding a live wire.
The power of God just rushes out of me into them. Their faith becomes active. Their faith was at the place where they believed they received. Faith is not of the head; it's of the heart.
Confession: Faith is of the heart. I believe I receive healing when hands are laid on me. I believe from my heart.
