Waiting on God is the subject of this psalm. It implies dependence and confidence, and both in such sort that we abide God's time: dependence, because we cannot do anything without Him, and ought not, because what He does is what the soul alone desires, because action without Him, even in self-defense, is only the action of our own will, and so our being without God so far. Saul did not wait upon God. He waited nearly seven days; but if he had felt he was dependent, and nothing could be done without God, he would have done nothing till Samuel came. He did not; he acted for himself and lost the kingdom. Deliverance from God is sweet; it is love; it is righteous, holy deliverance; it becomes the revelation of the favor and grace of God. It is perfect in time, way, and place. So where the soul waits for it, the will not being at work, it meets and enjoys the deliverance in this perfection; and we are perfect and complete in the will of God. But it implies confidence too; for why should we wait if God would not come in? The soul is thus sustained meanwhile. And this confidence is such that we tarry the Lord's leisure. Patience has its perfect work, so that we should be perfect and complete in all the will of God. There is too an active reckoning upon God. But this leaves the soul absolutely and exclusively waiting on Him. It is not active for itself; it waits only upon God. ("Truly" in verse 1, and "only" in verses 2, 4, 5, and 6 is the same word in Hebrew.)
The two points connected with it show the state of soul: "From Him cometh my salvation"; "My expectation is from Him." He only is the rock and salvation; so the confiding soul waits for Him, and seeks no other refuge—looks for deliverance only from Him. Hence, in principle (in fact, in Christ), the heart is perfect in its confidence, and meets in dependence the perfection of God; it accepts nothing but that, because it is assured that God is perfect and will act perfectly in the right time. Faith corresponds thus to the perfection of God. On the other hand, there is no working of self-will at all, no acceptance or saving of self by an intervention inferior in its nature to God Himself. This makes patient waiting on God a principle of immense moment. It characterizes faith in the Psalms, and so Christ Himself.
But there are a few points yet to remark. "Trust in Him at all times." There is constancy in this confidence, and constancy in all circumstances. If I look morally to Him, He is always competent, always the same; He does not change. I cannot act without Him, if I believe that He is only perfect in His ways. But, note, this does not suppose there is not exercise and trial of heart; or indeed waiting upon God would not have to be called for. But if God is faithful and awaits the time suited to the truth and His own character, so that His ways should be perfect, He is full of goodness and tender love to those who wait upon Him. He calls upon them to pour out their hearts before Him. How truly was this the case with Christ too! How in John 12, and above all in Gethsemane, He poured out His heart before God! God is always a refuge; He acts in the right time. He is always a refuge for the heart; and the heart realizes what He is when the deliverance is not come; and in some respects this is more precious than the deliverance itself. But it supposes integrity.
But yet another point. The effect of thus waiting upon God's deliverance is to make us know that it will be perfect and complete when it does come. "l shall not be moved." He had to wait, indeed, till God came in in perfection; but then His power secured from all. Man may think there is a resource in man, or in what man possesses, or in man's strength of will; but power, faith knows, belongs to God. The last verse shows that the soul is looking to the perfect divine righteousness of God's ways, but in the sense of integrity. The final intervention of God, the judgment He executes, will be the deliverance of the righteous. He has identified himself with God's ways on earth in heart, and waited till God makes them good, perfectly good, in power. But this will be the end of evil, and mercy to those who have sought good, and waited for God to avenge them. It will be a righteous reward to the expecting righteous man; his waiting will be met, and the power of evil set aside. In this path we have to walk. God deals so now in government, though not in its final accomplishment; but we have thus to count and wait upon Him.
