Surely God is my helper; the Lord is the sustainer of my soul.
PSALM 54 David has recorded in this psalm the prayers which he offered up to God when he heard of his having been betrayed by the Ziphites, and was reduced to a situation of extreme danger. It cannot fail to impress us with a high idea of his indomitable faith, thus to find him calling upon the name of God in the immediate prospect of death.
Commenting on Psalm 54:1-7
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.
We have here the lively actings of David's faith in his prayer, by which he was assured that the issue would be comfortable, though the attempt upon him was formidable. I. He was sure that he had God on his side, that God took his part (Psa 54:4); he speaks it with an air of triumph and exultation, Behold, God is my helper.
