Through the sacrament of Holy Communion (also known as the Lord's Supper), believers in Christ participate in Jesus' once-for-all sacrifice for sins on the cross (I Corinthians 10:16). The benefits of the cross: forgiveness of sins, resurrection life, communion with God - are all given to those who receive them by faith in the signs of bread and wine.
We are told in Scripture that we should examine ourselves before partaking of the Lord's Supper (I Corinthians 10:23-32). This examination consists of an appraisal of our lives in light of God's law, which is supremely expressed in the summary of the Law given by Jesus: that we should love God with all our heart, mind, soul, and strength; and that we should love our neighbor as our self. In examining ourselves, we accept God's offer of forgiveness in Christ, we intend to lead a new life and follow God's commandments, and we make amends to anyone that we have sinned against, seeking to forgive as we have been forgiven.
The following link is intended to exhort God's people to a proper examination of themselves before participating in worship and the Lord's Supper. This exhortation is especially appropriate to be read before services on Sunday mornings.
