Why is examining oneself important for the Lord's Supper?

In 1 Corinthians 11:27-29, Paul emphasizes the importance of examining oneself before partaking in the Lord's Supper. This self-examination is critical to ensure that participants are not partaking unworthily, which would make them guilty of the body and blood of the Lord. To 'discern the body' means to recognize the significance of Christ's sacrifice and the unity of believers as members of His body. This serious reflection helps individuals approach the Supper with the faith and reverence it demands, acknowledging their need for grace and Christ's redemptive work.
