What does the Bible say about self-examination before the Lord's Supper?

In 1 Corinthians 11:28-31, Paul emphasizes the importance of self-examination before partaking of the Lord's Supper. This examination involves determining whether one is coming to the table in a worthy manner, which includes being in right standing with God and free from unrepentant sin. The emphasis is not on sinless perfection, as no one is without sin, but rather on recognizing if one is living in habitual unrepentance. Being candid about our spiritual state is crucial, as failing to do so can lead to serious consequences, as articulated by Paul, who notes that some were weak, sickly, or had even died as a result of eating unworthily.
