Charles H. Spurgeon on Psalms 50:21

These things hast thou done, and I kept silence. No swift judgment overthrew the sinner —longsuffering reigned; no thunder was heard in threatening, and no bolt of fire was hurled in execution. Thou thoughtest that I was altogether such an one as thyself. The inference drawn from the Lord's patience was infamous; the respited culprit thought his judge to be one of the same order as himself. He offered sacrifice, and deemed it accepted; he continued in sin, and remained unpunished, and therefore he rudely said, "Why need believe these crazy prophets? God cares not how we live so long as we pay our tithes. Little does he consider how we get the plunder, so long as we bring a bullock to his altar." What will not men imagine of the Lord? At one time they liken the glory of Israel to a calf, and anon unto their brutish selves. But I will reprove thee. At last I will break silence and let them know my mind. And set them in order before thine eyes. I will marshall thy sins in battle array. I will make thee see them, I will put them down item by item, classified and arranged. Thou shalt know that if silent awhile, I was never blind or deaf. I will make thee perceive what thou hast tried to deny. I will leave the seat of mercy for the throne of judgment, and there I will let thee see how great the difference between thee and me.
