Verses 2, 5 and 12 contain three assurances that help us wait: God is our Salvation. God is our Expectation. God is our Vindication. Let's look closer at these three assurances.
God is our Salvation. David refers to salvation not from sin but from danger. "He only is my rock and my salvation; He is my defense; I shall not be greatly moved" (v. 2). David's enemies were pursuing him as usual. Saul was trying to kill him as usual. And yet David says, "I'm going to wait on the Lord. I'm not going to run around and lose control of myself. I'm going to wait on the Lord because from Him comes my salvation." That's true today also. We live in a dangerous world. We never know what may be just around the corner, but we have the assurance that God is our Rock and our Defense.
God is our Expectation. Where do you look for your expectation? To yourself, your wallet, your bankbook, your friends? Where do you look when the future seems bleak and dark? David looked to God. "My soul, wait silently for God alone, for my expectation is from Him" (v. 5).
God is our Vindication. It relieves us of a great deal of pressure and burden to know that we are not judges but witnesses. We are not here to vindicate ourselves. Our vindication comes from God, "who will render to each one according to his deeds" (Rom. 2:6). Today, as you face difficulties with people or things or circumstances, wait on the Lord. From Him come your salvation, your expectation and your vindication.
In troubled times, how often do you first look to yourself or others for answers before looking to God? If you look to God and wait for Him, He will see you through. Put God first and wait for Him to act on your behalf.
