The instruction for self-examination preceding the partaking of the Lord’s Supper is clearly taught here in Scripture. It is a solemn feast as we remember Christ’s body broken and blood shed for the remission of our sins. While we have been saved to the uttermost by the finished work of Christ on the cross which we commemorate at the holy feast, in our daily life and living, we may have transgressed the holy commandments of God. We need to confess our sins and ask for the Lord’s forgiveness.
