We have been looking for the past two weeks at the mediator and his work. We saw the way that Moses interceded for the people after their sin with the golden calf. We also saw how he put a stop to their sin and made them drink the product of their wickedness. The mediator does both things. He stops sin, and he asks God to forgive sin. We generally like to emphasize one or the other. Some of us are naturally pro-law, while others are pro-grace. But the Biblical account is perfectly balanced. The mediator is pro-law and pro-grace at the same time. We will see that once again in this evening's text, where Moses stands against sin and even kills sinners, but then goes to intercede for sinners too.
