What is the Lord’s Supper? How are we to remember Jesus? How can we remember someone who we do not know? Do we know Jesus personally? If we do not know Him, we cannot remember Him.
Participating in the Sacrament will not save anyone. Salvation is by faith in Jesus Christ. It is not brought about by swallowing any amount of bread and wine, however consecrated it may be, but is a work of the Holy Spirit of God. If you are outside the Lord Jesus Christ, you need to cry to God that He might have mercy on you.
