What does it mean to examine ourselves before partaking in the Lord's Supper?

In 1 Corinthians 11:28, Paul instructs believers to examine themselves prior to taking part in the Lord's Supper. This self-examination is a moment of reflection on our spiritual condition and acknowledgment of Christ's sacrifice. It involves recognizing our insufficiency and reliance on Christ's righteousness alone for acceptance before God. By doing so, we partake in the supper not out of ritual but as a sincere proclamation of our faith and gratitude for the grace received through Christ. It serves as a reminder of the unity in the body of believers and our collective need for redemption.
