We doubt ourselves because we should doubt ourselves. When we have faith in God, we trust that God has a plan. When we trust that God has a plan, we will have peace because we know that His plan is always better than our plan. However, when we rely on our own experience and our own wisdom, we tend to doubt and we are unsettled and worry because we know that although we want to be in control and we think we are capable, we know full well that we are not. We are definitely not as capable as God.
Lord, help me to trust You more so that I may experience more peace.
