It is God that girdeth me with strength, and maketh my way perfect.
David’s song of thanks: it is God who girds him with strength and makes his way perfect.
KJV29For by thee I have run through a troop; and by my God have I leaped over a wall. 30As for God, his way is perfect: the word of the Lord is tried: he is a buckler to all those that trust in him. 31For who is God save the Lord? or who is a rock save our God? 32It is God that girdeth me with strength, and maketh my way perfect. 33He maketh my feet like hinds’ feet, and setteth me upon my high places. 34He teacheth my hands to war, so that a bow of steel is broken by mine arms. 35Thou hast also given me the shield of thy salvation: and thy right hand hath holden me up, and thy gentleness hath made me great.
Israel’s prayer book: songs of trust, lament, thanks and praise, many of them by David.
The Lord is my strength and song, and he is become my salvation: he is my God, and I will prepare him an habitation; my father’s God, and I will exalt him.
Israel’s song after crossing the sea: the Lord is my strength and my song, and He has become my salvation.
Finally, my brethren, be strong in the Lord, and in the power of his might.
Strength that does not depend on you: be strong in the Lord and His mighty power.
The Lord is my light and my salvation; whom shall I fear? the Lord is the strength of my life; of whom shall I be afraid?
If the Lord is your light and salvation, whom shall you fear?
My flesh and my heart faileth: but God is the strength of my heart, and my portion for ever.
Written by someone whose body and heart were giving out: God remains the strength of the heart when everything else fails.
