Charles H. Spurgeon on Psalms 118:6

The LORD is on my side, or, he is "for me." Once his justice was against me, but now he is my reconciled God, and engaged on my behalf. The Psalmist naturally rejoiced in the divine help; all men turned against him, but God was his defender and advocate, accomplishing the divine purposes of his grace. The expression may also be translated "to me, "that is to say, Jehovah belongs to me, and is mine. What infinite wealth is here! If we do not magnify the Lord we are of all men most brutish. I will not fear. He does not say that he should not suffer, but that he would not fear: the favour of God infinitely outweighed the hatred of men, therefore setting the one against the other he felt that he had no reason to be afraid. He was calm and confident, though surrounded with enemies, and so let all believers be, for thus they honour God. What can man do unto me? He can do nothing more than God permits; at the very uttermost he can only kill the body, but he hath no more that he can do. God having purposed to set his servant upon the throne, the whole race of mankind could do nothing to thwart the divine decree: the settled purpose of Jehovah's heart could not be turned aside, nor its accomplishment delayed, much less prevented, by the most rancorous hostility of the most powerful of men. Saul sought to slay David, but David outlived Saul, and sat upon his throne. Scribe and Pharisee, priest and Herodian, united in opposing the Christ of God, but he is exalted on high none the less because of their enmity. The mightiest man is a puny thing when he stands in opposition to God, yea, he shrinks into utter nothingness. It were a pity to be afraid of such a pitiful, miserable, despicable object as a man opposed to the almighty God. The Psalmist here speaks like a champion throwing down the gauntlet to all comers, defying the universe in arms; a true Bayard, without fear and without reproach, he enjoys God's favour, and he defies every foe.
