Psalms 18:3

"My God." Here he sets forth the affection of hope. And there is a difference between hope and love, because love is a unitive power -- for we love something insofar as we consider it our own; and therefore he says that God is his …

He sets himself to magnify the deliverances God had wrought for him, that he might be the more affected in his returns of praise. It is good for us to observe all the circumstances of a mercy, which magnify the power of God and his goodness to us in it. The more imminent and threatening the danger was out of which we were delivered the greater is the mercy of the deliverance.

I will call upon the Lord,.... In prayer, for fresh mercies, and further appearances of himself, and discoveries of his grace and favour; who is worthy to be praised; for the perfections of his nature, the works of his hands, his providential goodness, and more especially for his covenant grace and blessings in Christ.

In this verse the happy poet resolves to invoke the Lord in joyful song, believing that in all future conflicts his God would deal as well with him as in the past. It is well to pray to God as to one who deserves to be praised, for then we plead in a happy and confident manner. If I feel that I can and do bless the Lord for all his past goodness, I am bold to ask great things of him. That word So has much in it. To be saved singing is to be saved indeed. Many are saved mourning and doubting; but David had such faith that he could fight singing, and win the battle with a song still upon his lips. How happy a thing to receive fresh mercy with a heart already sensible of mercy enjoyed, and to anticipate new trials with a confidence based upon past experiences of divine love! No fearing or doubting with Christ on our side, We hope to die shouting, 'The Lord will provide.'"

I will call upon the Lord - When he was conscious that the object of his worship was such as he has pointed out in the above nine particulars, it is no wonder that he resolves to call upon him; and no wonder that he expects, in consequence, to be saved from his enemies; for who can destroy him whom such a God undertakes to save?

I will call upon the Lord - The idea here is, that he would constantly call upon the Lord. In all times of trouble and danger he would go to him, and invoke his aid. The experience of the past had been such as to lead him to put confidence in him in all time to come. He had learned to flee to him in danger, and he had never put his trust in him in vain. The idea is, that a proper view of God’s dealings with us in the past should lead us to feel that we may put confidence in him in the future. Who is worthy to be praised - More literally, “Him who is to be praised I will call upon, Jehovah.” The prominent - the leading thought is, that God is a being every way worthy of praise. So shall I be saved from my enemies - Ever onward, and at all times. He had had such ample experience of his protection that he could confide in him as one who would deliver him from all his foes.
