Water baptism represents being cleansed from and dying to sin. However, our salvation is through belief in Jesus (Rev 1:5; 1 Pet 1:18–19). Baptism by full immersion allows the believer to follow Jesus’ example (Matt 3:13–17) and full immersion best symbolizes being buried and raised into a new life in Christ (Rom 6:4).
During the Passover Celebration with His disciples on the night of His arrest, Jesus instituted the ordinance of Communion. He broke bread and served wine, telling His disciples to take them in remembrance of Him and His sacrifice for them (Luke 22:14-20). This illustration, which we still practice today, powerfully symbolizes Jesus’ sacrifice on the cross for us, as the true Lamb of God (John 1:29).
Usually observed on Maundy Thursday (the day before Good Friday), this ordinance helps us to recall when Jesus’ performed this service for His disciples at the Passover meal (John 13:1-15). In obedience to Jesus’ command, and in following his example, we humble ourselves to wash each other’s feet. In doing this we remember and honor Christ’s humble sacrifice, and we also humble ourselves as we serve and love one another in an unconventional and undignified way.
