Why should Christians examine themselves before taking the Lord's Supper?

Self-examination before partaking in the Lord's Supper is crucial, as Paul instructs believers to 'let a man examine himself' (1 Corinthians 11:28). This introspection is meant to affirm one's faith in the sufficiency of Christ's sacrifice and acknowledge the salvation provided through His death. Failing to discern the body of Christ risks taking the cup and bread in an unworthy manner, bringing judgment upon oneself. The emphasis is on understanding that all righteousness and salvation are found in Christ alone, fostering a genuine appreciation for the grace bestowed upon believers.
