Worthy partakers are those who confess their sins in self-abhorrence, humiliation, faith in God's promises, and gratefulness of heart. This is the 'worthiness' that belongs to the Lord's Supper. It is not at all meritorious in nature, but is in complete harmony with what is signified and sealed in the Lord's Supper. It is a worthiness that coincides with a confession of 'unworthiness' and with trust in the salvation of God.
