Notice the personal nature of this promise: "I will." The Lord Jehovah Himself intervenes to deliver and redeem His people. He pledges Himself personally to rescue them. His own arm shall do it, in order that He may have the glory. Not a word is said of any effort of our own that may be needed to assist the Lord. Neither our strength nor our weakness is taken into account, but the lone "I," like the sun in the heavens, shines out resplendent in complete sufficiency. Why then do we allow ourselves to be wounded by calculating our forces and consulting with mere men? God has enough power without borrowing from our puny arm.
To enjoy peace, our unbelieving thoughts must be stilled, and we must learn that the Lord reigns. There is not even a hint of help from any secondary source. The Lord says nothing of friends and helpers: He undertakes the work alone and feels no need of human arms to aid Him. All our looking around to companions and relatives are vain; they are broken reeds if we lean upon them—often unwilling when able, and unable when they are willing. Since the promise comes from God alone, it is best for us to wait only on Him; and when we do so, our expectation never fails us.
Who are the wicked, that we should fear them? The Lord will utterly consume them; they are to be pitied rather than feared. As for terrible ones, they are only terrors to those who have no God to turn to, for when the Lord is on our side, whom shall we fear? If we run into sin to please the wicked, we have cause to be alarmed; but if we maintain our integrity, the rage of tyrants will be overruled for our good. When the fish swallowed Jonah, he found him a morsel that he could not digest; and when the world devours the church, it is glad to be rid of it again. In all occasions of fiery trial, let us maintain our souls in patience.
