On that one great day of the year, the Day of Atonement, the high priest alone through past the veil into the second chamber of the tabernacle, the holy of holies. He went in first with the golden censer, and then with the sin offering for himself, and finally with the sin offering for the people (Leviticus 16:12-15).
Let no one say, ‘I sinned in error; therefore it cannot be counted against me.’ The law recognised a particular category of sins called sins of ignorance (Leviticus 4), but they were still sins and still needed to be purged away by sacrifice. These are not unintentional sins, as if we did not know we were sinning. They are sins in which there is an element of misunderstanding as well. Perhaps we ignorantly underestimate the seriousness of what we are doing, or we fail to be on our guard, or we deceive ourselves that we can go a certain distance down the path of sin and then turn back. Ignorance is no excuse, for much of our ignorance is self-induced, and comes from not diligently studying God’s will, or from not wanting to know reasons why we should not indulge our favourite sins.
