Charles H. Spurgeon on Psalms 111:7

The works of God expound his word, in his works his word is often made visible. That's an excellent expression, The works of his hands are verity and judgment. The acts of God are verity, that is, God acts his own truths. As the works of our hands ought to be the verity and judgments of God, (every action of a Christian ought to be one of Christ's truths), so it is with God himself; the works of his hands are his own verity and judgments. When we cannot find the meaning of God in his word, we may find it in his works: his works are a comment, an infallible comment upon his word. —Joseph Caryl.

Verses 7-8. God is known to be faithful and just both in his works and in his word, insomuch that the most beautiful harmony is apparent between the things he has spoken and those he has done. This wonderfully confirms the hope and faith of the godly. —Mollerus.
