I had a blog relative to Gill a few days back. I received this via e-mail yesterday and thought some would be interested in this quote.
"Thy God hath commanded thy strength: strengthen, O God, that which thou hast wrought for us....O God, thou art majestic out of thy holy places: the God of Israel is he that giveth strength and power unto his people. Blessed be God" (Psa. 68:28 & 35).
John Gill on these verses: "For this work sometimes seems to be very low and weak, and needs strengthening, and it is God only that can do it, and he will do it (I Peter 5:10); and this shows that the grace of God is not only necessary at first conversion, but to be continued for the performing of the work of grace until the day of Christ....His peculiar covenant-people, his Israel he is the God of. These are weak, and encompassed with infirmities; he has strength in himself for them; he has promised it to them, and he gives it to them as a pure gift and unmerited favor of his" (Gill's Commentary on the Psalms).
