On Sunday, Paul Priest preached a great sermon on following verses from James:
If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him. But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind. For that person must not suppose that he will receive anything from the Lord; he is a double-minded man, unstable in all his ways.
To guide your listening, he lists three main points from the text.
1. Prayer must be definite. We must ask.
2. Prayer must be dogmatic. We must ask in faith.
3. Prayer must be decisive. We must ask without doubting.
