Romans 10:10 -- For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
When you believed in your heart and confessed with your mouth that Jesus Christ is Lord -- when you received Him as your saviour -- that is called the "Great Confession".
But if you do not know how to fight the good fight of faith -- How to stay in the faith fight until you win -- your confession becomes null, void, powerless, and of no use to you in this life.
Proverbs 18:20 -- A man's belly shall be satisfied with the fruits of his mouth: and with the increase of his lips shall he be filled.
QUESTIONS TO ASK MYSELF:

How does my confession become powerful?
