John Calvin Commentary Psalms 111:7

"The works of his hands are truth and justice; All his precepts are sure." — Psalms 111:7 (ASV)

The works of his hands. In the first clause of the verse, he exclaims that God is known to be faithful and upright in His works. Then he goes on to extol the same truth and rectitude as pervading the doctrine of the Law. The sum of this is that a beautiful harmony characterizes all the sayings and doings of God, because everywhere He shows Himself to be just and faithful.

We have a memorable proof of this fact in the redemption of His ancient people. Yet I do not doubt that, under the term works, the prophet includes the constant government of the Church, because God daily and unceasingly shows that He is just and true, and unweariedly pursues the same course.

Among men, it is considered more important for one to be found just in practice than in profession. Yet, as the doctrine of the Law was the very life and safety of the people, the prophet very properly, and in several expressions, dwells upon the sentiment contained in the second clause of the verse, saying, all his statutes are true, they are established forever, and are drawn up in perfect accordance with the strict law of truth and equity.

And assuredly, if God had not kept the people united to Him by the sacred chain of the Law, the fruit of their redemption would have been very small, and even that benefit would have soon been lost by them. We ought to observe, then, that this subject is brought prominently forward in this place because, in attesting the eternal love of God, it became the means of imparting life.
