When we hear God’s Word our mouths are shut (Romans 3:19). We recognize that we are answerable to God and that we have no good answer, we have no good works that can answer and satisfy His righteous requirements (Romans 3:20). We are silenced.
And yet thankfully, we are not finished. The next verse proclaims: “But now the righteousness of God has been manifested apart from the law…through faith in Jesus Christ for all who believe” (Romans 3:21). In our flesh we have no defense, but by faith in Christ Jesus we have peace with God (Romans 5:1), we have no condemnation (Romans 8:1).
We still fight against the accuser. The great dragon, the ancient serpent, called the devil and Satan (Revelation 12:9) is the “accuser of our brothers…who accuses them day and night before God” (Revelation 12:10). Does he accuse you? Does he take the law and use it against you?
Thomas Watson wrote, “some Christians are so skillful at…accusing themselves for want of grace, [it is] as if they had received a fee from Satan, to plead for him, against themselves.” But you ought instead to “tell satan when he accuseth thee, it is true the debt is mine, but go to…Christ, He will discharge it.”
This is what we proclaim when we eat and drink the Lord’s Supper. We proclaim that as those under sin, our flesh and blood were required, but that as those in Christ, His flesh and His blood were spent on our behalf. So by faith, we cling to the death and resurrection of Christ and the accusers mouth is shut. By faith, one little feast shall fell him.
