Charles H. Spurgeon on Psalms 147:20

He hath not dealt so with any nation. Israel had clear and exclusive knowledge of God, while others were left in ignorance. Election is the loudest call for grateful adoration. And as for his judgments, they have not known them; or, and judgments they had not known them, as if not knowing the laws of God, they might be looked upon as having no laws at all worth mentioning. The nations were covered with darkness, and only Israel sat in the light. This was sovereign grace in its fullest noontide of power. Praise ye the Lord. When we have mentioned electing, distinguishing love, our praise can rise no higher, and therefore we close with one more hallelujah.
