We have all been, and will find ourselves again, in a place of uncertainty, not knowing what we should do. OUR plan isn't working out and we feel lost. God has a plan. He always does. The "what do I do" doesn't pertain to the actual steps we should take but "what do I do" is a simple reminder to pray and ask God to help us understand what we SHOULD do.
Lord, my plans typically fail because they are my plans so help me pray more and ask what Your plan is for me and my life.
