You believe in your heart, and you confess it with your mouth.

But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; that if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
(Rom. 10:8-10)
The word "salvation" not only means the saving of your soul where you'll spend eternity in the presence of God forever, but the word salvation is all inclusive of everything that mankind needs. It means wholeness, soundness, safety, deliverance, peace, healing, prosperity, preservation.

Whatever it is that you need, it is available to you, and it only comes by believing in your heart and confessing it with your mouth.

Where is faith? It's in two places. Faith is in your heart, and faith is in your mouth. What's in your heart has to come out of your mouth.

I don't believe in a silent religion. What's in your heart will come out of your mouth.
