We give up so easily in prayer. We pray once and if God doesn’t answer, we assume He is not listening. Or, we make the mistake of getting some vague conviction from God and fill in all the practical loose ends with our ingenuity and strategic planning. In 2 Samuel 2:1-2, shortly after Saul is killed, David inquires of the Lord about what he should do next and the Lord’s initial response is a vague, "Go up" (to one of the towns of Judah).
Instead of second guessing God and figuring out on his own which city God meant, David inquires again. He abandons his intuition, his trust in his leadership, and trusts fully God’s will for his life. It is unclear if David knew that he would be anointed king of Judah in the city of Hebron. In this small way, we see how much David trusted God with every detail of his life.
When we pray, God may give an initial direction, but we must not in our excitement be too quick to act and plan and prepare and leave God out in the process. We must pray again for clarification. We must pray for continual direction. We must pray as an expression of our utter dependence on Him.
