Psalms 115:12, “The LORD hath been mindful of us: he will bless us..”
It is true that we have not always been mindful of the Lord, as the Word tells us in Deuteronomy 32:18; “Of the Rock that begat thee thou art unmindful, and hast forgotten God that formed thee.” Though we have forgotten Him, He has never been unmindful of us.
The Lord “remembered us in our low estate: for his mercy endureth for ever” (Psalm 136:23). “Can a woman forget her sucking child, that she should not have compassion on the son of her womb? yea, they may forget, yet will I not forget thee. Behold, I have graven thee upon the palms of my hands; thy walls are continually before me” (Isaiah 49:15-16). He therefore has never ceased to be mindful of our needs and burdens. He is mindful of our prayers to Him and His promises to us. When we are weak and frail, “he knoweth our frame; he remembereth that we are dust” (Psalm 103:14). The Lord is always thinking about us.
It is because He hath been mindful of us in the past, that we can confidently assert He will bless us in the future. As John Trapp has said, “God hath, and therefore God will, is an ordinary Scripture argument.”
“God's compassions to his people infinitely exceed those of the tenderest parents towards their children. What are the affections of nature to those of the God of nature!” (Matthew Henry 1662-1714).
