Charles H. Spurgeon on Psalms 111:8

Are done. Ps 111:7-8 contains a precious meaning for the soul whose rest is in the finished work of Christ. Jehovah has commanded, giving it in trust to Jesus to make sure, in perfect obedience, the word of truth and holiness. The commandment therefore has been "done." It has been done in truth and uprightness by him whose meat it was to do it; who willingly received it with a knowledge of its end, and in whose accomplishment of it the believing sinner finds his assurance of eternal peace. Joh 12:50. Jesus held the law within his heart, to keep it there for ever. As the fulfiller in truth of the commandment, he has become its end for righteousness to every believer in his name. —Arthur Pridham.
