Psalms 56:9

"In whatsoever day I shall have called upon You, behold I have known that my God are You" [Psalm 56:9]. A great knowledge. He says not, "I have known that God You are:" but, "that my God are You." For yours He is, when you He succours: yours He is, when thou to Him art not an alien. Whence is said, "Blessed the people of whom is the Lord the God of the same." Wherefore "of whom is"? For of whom is He not? Of all things indeed God He is: but of those men the God peculiarly He is said to be, that love Him, that hold Him, that possess Him, that worship Him, as though belonging to His own House: the great family of Him are they, redeemed by the great blood of the Only Son. How great a thing has God given to us, that His own we should be, and He should be ours! But in truth foreigners afar have been put from holy men, sons alien they are. See what of them is said in another Psalm: "O Lord, deliver me," he says, "from the hand of alien sons, of whom the mouth has spoken vanity, and the right hand of them is a right hand of iniquity.". ..

When I cry unto thee,....

When I cry unto thee, then shall mine enemies turn back. So soon as I pray they shall fly. So surely as I cry they shall be put to the rout. The machinery of prayer is not always visible, but it is most efficient. God inclines us to pray, we cry in anguish of heart, he hears, he acts, the enemy is turned back. What irresistible artillery is this which wins the battle as soon as its report is heard! What a God is this who harkens to the cry of his children, and in a moment delivers them from the mightiest adversaries! This I know. This is one of the believer's certainties, his axioms, his infallible, indisputable verities. For God is for me. This, we know, and we know, therefore, that none can be against us who are worth a moment's fear. "If God be for us, who can be against us?" Who will restrain prayer when it is so potent? Who will seek any other ally than God, who is instantly present so soon as we give the ordained signal, by which we testify both our need and our confidence?

When I cry unto thee, then shall mine enemies turn back - As soon as they know that I call upon thee, then, knowing that thou wilt hear and save, my enemies will immediately take flight. The cry of faith and prayer to God is more dreadful to our spiritual foes than the war-whoop of the Indian is to his surprised brother savages. This I know - I have often had experience of the Divine interposition; and I know it will be so now, for God is with me. He who has God With him need not fear the face of any adversary.

When I cry unto thee - This expresses strong confidence in prayer. The psalmist felt that he had only to cry unto God, to secure the overthrow of his enemies. God had all power, and his power would be put forth in answer to prayer. Then shall mine enemies turn back - Then shall they cease to pursue and persecute me. He did not doubt that this would be the ultimate result - that this blessing would be conferred, though it might be delayed, and though his faith and patience might be greatly tried. For God is for me - He is on my side; and he is with me in my wanderings. Compare the notes at Rom 8:31.
