Psalm 143 seems to be a continuation of Psalm 142. In this Psalm David follows a pattern of wrestling with a problem and then crying out to God for help. So many times David finds himself in trouble and despair, but always finds his help in God.
What an encouragement this is to all of us. If David, a man after God's own heart, faced such troubles, then we should not be surprised when we continually face such trouble as well. The question is, “How should we react when we do?”
The answer is found in verse five where David writes, “I remember the days of old; I meditate on all You have done.” Meaning, we simply look to what God has done for us in the past, and realize He will continue to deliver us in the future. For we are His children, the work of His hands, redeemed by the blood of Christ, who will not allow our foot be moved.
The Truth: “The Lord will keep you from all harm, He will watch over your life; the Lord will watch over your coming and going both now and forevermore.” (Psalm 121:7-8)
