Before Jesus and his disciples ate the Passover supper, Jesus washed the feet of his disciples. Jesus taught them that He is their example, and that they should do the things He did. He taught them about how important it is to love and show love. He commanded them to love one another, just as He had loved them. 

Jesus was not only talking to His twelve disciples, He was teaching all those who follow Him. We should try to show love to one another, keep the commandments to show love for Jesus Christ, and remember the love Jesus has for us and the sacrifice he made for us. The sacrament is an opportunity to remember Jesus Christ each week and renew our promise to always remember Him.
