Did you know that, according to the Word of God, there is no lack in the Body of Christ? Everything we could ever need, every problem we could ever face has been covered by the blood of Jesus. His exceeding great and precious promises have supplied it all.
Why then do many of us keep on suffering lack? Because we haven't, as Hebrews 5:13 says, become skillful in the Word of righteousness.
It takes skill to apply the Word of God. Sometimes we just sling the Word around and try to use it any old way. We pray some ignorant prayer and then say, "Oh well, God knows what I mean" and expect it to be answered.
