David was hiding in a cave when he wrote this one. You have to imagine how he felt. He described himself as “weary from distress”. This young man had been anointed as the next king by the great prophet Samuel, he had defeated every enemy he faced, he had married the king’s daughter, but now he was hunted like a dangerous animal by his father-in-law and all of the king’s supporters.
David was physically weary, but he was not depressed. He prayed asking God to protect him. He believed God would “send help from heaven to rescue me”. He said he was confident in God, and he wanted to sing and play his harp in praise to God. How could David be so confident and upbeat in his circumstances? What was his secret? How would we react if we were in difficult circumstances?
David said he cried out to God “Who will fulfill His purpose for me”. God has a purpose for everyone He created. God had a purpose for Noah; He used Noah to save the human race. God had a purpose for Abraham; God chose him at the age of 75 to build a nation to spread the news about the promised Messiah. God had a purpose for Moses; God chose him at the age of 80 to deliver the Israelites from Egypt. God had a plan for Pharaoh because he rejected God; God demonstrated His power on the Egyptians because they refused to acknowledge God. The examples are many throughout the Bible and history.
The question we should ask ourselves is “what is God’s purpose for me”? Some of us will find God’s purpose early in life. Some of us will be like Moses and think we know what God wants us to do, but because of circumstances or failure will find God’s purpose much later in life. The question isn’t so much when we find it, but are we looking for it?
