In Psalm 31:14-15, David says: “I say You are my God, my times are in Your hand.” Here David exhibits a trust in the Lord despite the enemies which the earlier part of the Psalm referred to. Verse 15 exhibits a calm assurance: “My times are in Your hand.” But notice what the SOURCE of that assurance was.
It came from the COMMITMENT he had to God, which was found at the end of :14, “I say You are my God.” These two are inextricably linked. Because David knew that God was truly HIS God, he knew that his times were in His hand. His certain commitment TO God, and the assurance he received FROM God, went hand in hand.
It will be the same with us. We can have a confident assurance that God will take care of the things that concern us, when we know for certain that He is our God. Say to Him as David did: “You are my God”, and you can be as certain as he was that “my times are in Your hand”!
