Let us first look at home. “I am a man of unclean lips” (Isa 6:5), i.e., I am a sinner. This confession suits us and is readily made by all who know themselves. The Lord said of the Amorites at a certain period, “Their iniquity is not yet full” (Gen 15:16)! I hope the measure of our iniquity is not yet full, but it is filling every day, and we are all daily contributing to fill it. True believers, though by grace delivered from the reigning power of sin, are still sinners. In many things we offend all, in thought, word, and deed. We are now called upon to humble ourselves before God, for the sins of our ignorance, and for the more aggravated sins we have committed against light and experience—for those personal sins, the record of which is only known to God and our consciences; for the defects and defilements of our best services; for our great and manifold failures in the discharge of our relative duties, as parents, children, husbands, wives, masters, or servants, and as members of the community. Our dullness in the ways of God; our alertness in the pursuit of our own will and way; our differences to what concerns His glory, compared with the quickness of our apprehensions when our own temporal interests are affected—are so many proofs of our ingratitude and depravity.
The sins of the Lord’s own people are so many, and so heightened by the consideration of His known goodness, that if He was to enter into judgment with them only, they could offer no other plea than that which He has mercifully provided for them: “If thou, LORD, shouldest mark iniquities, O Lord, who shall stand? But there is forgiveness with thee, that thou mayest be feared” (Psa 130:3-4).
