Incoherent to you, others understood.
Faith comes from the word. Faith is not simply the work of a man's volition (will). Hebrews tells us faith is assurance and conviction. (Heb.11:1) There is an absolute certainty when one has faith, a certainty you will literally stake your life on. I can say "I believe God cares for me", but it's not till I get in the "sticky" situation do I see whether I truly have faith or whether I am simply relying on the strength of my own will.
Your inability to understand how a man can use His volition to agree with God when shown the truth is most likely why you don't comprehend what I said. You speak as if you are just a puppet, unable to do even the things God created us to do by design. Men can believe whatever they want, but it takes believing the truth in order to have faith. The word is truth and only when it is working in your soul does a man have faith.
Psalm 119:11
Your word I have hidden in my heart, That I might not sin against You.
You hide the word in your heart by believing on it and keep on believing but it is the word (truth) that has the power of faith, not our willingness to believe. God honours His word and saves the believer. The most power our wills have is to reveal who we are.
