Looking at our corporate service from an unbeliever’s point of view, how ridiculous must it seem for us to confess our sins as part of our worship? What idiots would assemble in order to acknowledge their failures? From an outsider’s perspective, why would anyone go to get worked over like this?
If you were an unbeliever, and if you were forced to acknowledge that God exists, you wouldn’t want Him to be authoritative. If forced to acknowledge that He is authoritative, you wouldn’t want Him to holy. If forced to acknowledge that He is holy, you wouldn’t want Him to made His standards known. If He did make His law known, you wouldn’t want Him to offer forgiveness as easy as asking for it. To an outsider, confessing sins is ridiculous all the way down the line.
Turn it around though. From a believer’s perspective, how advantageous is it for us to confess our sins like this? Think about how many things we proclaim without even using words. In our confession of sin we confirm the existence of God; we confess to someone. Without words we affirm God’s authority over us. We acknowledge His holiness, that He has a standard. We recognize that He has revealed His standard; we can’t claim ignorance. We affirm that He cares, that He hears us. We admit that we are guilty, that what He said about us is true. We assert that we can’t buy or work our way out of guilt. We declare our belief in the free forgiveness of the gospel, in the sacrifice of God’s Son.
How advantageous for us! How economical! In one element of worship we honor His existence, His authority, His holiness, His revelation, His love, His sacrifice, His forgiveness. If only all of our worship was as easy as confessing our sins.
Note: I also gave this exhortation in 2012.
