22 Do you have faith? Have it to yourself before God. Happy is he who does not condemn himself in what he approves. 23 But he who doubts is condemned if he eats, because he does not eat from faith; for whatever is not from faith is sin (Romans 14:22, 23).
Have you ever wanted something, and your conscience just gives you fits? You want it, and yet you condemn yourself for wanting it. It is the gift of faith that God gives us that accomplishes what we believe and say. Doubting our own faith projects causes them to fail, as well they should. From the beginning we should talk with the Lord about our faith projects and find out what He wants. He, after all, designed a certain specific destiny for each of us, and we must use our gifts for that destiny and make our faith grow to fulfill that destiny. If we refuse to grow in faith, then we will be weak in our trust in God.
The righteousness of faith uses words. It is words of faith that brings a thing into reality. We believe in our hearts, we trust, and with our mouths we speak words of faith. But first, we find out what God wants, and we put our faith in that!
