Charles H. Spurgeon on Psalms 54:4

Behold, God is mine helper. He saw enemies everywhere, and now to his joy as he looks upon the band of his defenders he sees one whose aid is better than all the help of men; he is overwhelmed with joy at recognizing his divine champion, and cries, Behold. And is not this a theme for pious exultation in all time, that the great God protects us, his own people: what matters the number or violence of our foes when HE uplifts the shield of his omnipotence to guard us, and the sword of his power to aid us? Little care we for the defiance of the foe while we have the defence of God. The Lord is with them that uphold my soul. The reigning Lord, the great Adonai is in the camp of my defenders. Here was a greater champion than any of the three mighties, or than all the valiant men who chose David for their captain. The psalmist was very confident, he felt so thoroughly that his heart was on the Lord's side that he was sure God was on his side. He asked in the first verse for deliverance, and here he returns thanks for upholding: while we are seeking one mercy which we have not, we must not be unmindful of another which we have. It is a great mercy to have some friends left us, but a greater mercy still to see the Lord among them, for like so many cyphers our friends stand for nothing till the Lord sets himself as a great unit in the front of them.
