Just as the living Father sent me and I live because of the Father, so also the one who feeds on Me will live because of me. (John 6:57)
Baptism that Christ offers in Matthew 28 is that of faith in the triune God. Baptism requires us to be dead to the sinful desires of the world and to rise again to live for Christ. It is a totally new experience that requires us to live a new life of dedication to Christ. Baptism of a believer will culminate in his resurrection on Christ's return. A baptized Christian life is a constant struggle with evil forces of the world. These forces have to be defeated through a life of prayer and meditation on God's word. Merely dying for Christ is not enough; one has to live for Christ.
The Lord's Supper, a replica of the feast of Passover, has something more to offer than the Passover initiated during the exodus. The first Passover temporarily saved Israelites from physical death but the second Passover saves believers for eternity. In order to walk with Christ one has to have communion with him through his body and blood. This body and blood unifies us with Christ making us co-heirs of the kingdom of God. The Lord's Supper provides us not only an opportunity to stay with Christ but that through this Christ enters our physical body making our body his temple. Therefore, the work that begins in believers through baptism will be strengthened through Lord's Supper and both will take us to eternal life.
Thank you, Lord for providing us the opportunity to be baptized in your faith. Grant that we may live and walk with you. Amen.
