Why should believers examine themselves before the Lord's Supper?

Self-examination before partaking in the Lord's Supper is crucial for believers to reflect on their faith, repentance, and the seriousness of their participation. In 1 Corinthians 11:28-29, Paul emphasizes the importance of examining one's heart and motives, as taking part in the Supper without regard for its meaning can lead to condemnation. This practice is not about achieving perfection but rather about recognizing one's sinfulness and the grace offered through Christ's sacrifice. It serves as a vital reminder of the ongoing need for repentance and dependence on God's grace. Through this examination, believers affirm their faith in Christ and the work He accomplished on their behalf, preparing their hearts to fully engage in this sacred ordinance.
