When Jesus appears for the last time to his disciples, he sends them out into the world saying: “Go, … make disciples of all nations; baptise them in the name of the Father and of the Son and of the Holy Spirit” (Matthew 28:19).
Jesus offers us baptism as the way to enter into communion with God, Father, Son, and Spirit, and to live our lives as God’s beloved children. Through baptism we say no to the world. We declare that we no longer want to remain children of the darkness but want to become children of the light, God’s children. We do not want to escape the world, but we want to live in it without belonging to it. That is what baptism enables us to do.
