When we worry we deny God's sovereignty. We assume that sovereignty to ourselves. If God is not sovereign we better worry. If God is alive and well, there is no need to worry. Prayer is a panacea for anything we face.
People say there are no panaceas anymore.
God teaches us that there is a panacea in prayer. There is nothing about which we cannot pray. God concerns himself with every detail of our lives. God cares about everything we face. He cares about our relationships.
