Charles H. Spurgeon on Psalms 19:5

"Which is as a bridegroom," etc. The sun is described like a bridegroom coming out of his chamber, dressed and prepared, and as a giant rejoicing to run his race; but though the sun be thus prepared, and dressed, and ready, yet if the Lord send a writ and a prohibition to the sun to keep within his chamber, he cannot come forth, his journey is stopped. Thus also he stops man in his nearest preparation for any action. If the Lord will work, who shall let it? Isaiah 43:13. That is, there is no power in heaven or earth which can hinder him. But if the Lord will let, who shall work? Neither sun, nor stars, nor men, nor devils, can work, if he forbids them. The point is full of comfort. —Joseph Caryl.
