B before C

To believe is to accept something as real and true, it is a prerequisite for confessing. Confession is a formulary of faith, and faith, believing without evidence, comes by hearing God. Without believing, confessing is fake, fraud, and flattery, like a tree without roots.

Confessing scriptures without believing in your heart is mere positive speaking; heart work must precede mouth talk. Trying to work out the words of God on lips alone can be compared to an attempt to run a program not installed on a computer by mere copying of its desktop icon. Nothing will happen when you click, except that you will get a message reminding you of your error.

Believing installs the word of God in the heart while confessing activates it. Lip service cannot effect any positive change or deliver any meaningful result. Confessing without believing may result in shame and ridicule, but anyone who believes in Him will not be disappointed. The saying is true: if you believe, you will receive.
