Christ's baptism in the Jordan by John's hand is the baptism of the world. Every creature, every made thing is washed clean, made holy, and brought into a new creation. God's human creatures are given the freedom to follow Christ's example in baptism, or to continue as natural creatures until death. But because each of us is gifted with an immortal soul, the decision to continue on as a natural creature has consequences beyond death. Without God's mercy, without receiving His forgiveness, we perish by being forever separated from Him. Baptism brings us into the life of Christ and sets us on the narrow way toward our destined freedom in His love. Baptism makes possible every other means of receiving God's gifts. Baptism is the first but not the only invitation we get to come and enjoy the blessings of God's generosity. Why would we choose to remain natural creatures when our supernatural end is provided free of charge? Why would we remain in sin when our freedom from sin is already paid for, already purchased?
Our Lord is blessed and baptized to fulfill all righteousness under the Law. His baptism reveals his nature and mission: he is the Christ sent to save the world from sin and death. His offer of mercy and forgiveness is made daily, hourly and all we need to do is accept his offer and thrive in holiness. When we come to Him in humility with thanksgiving, He says to each one of us: “You are my beloved child; with you I am well pleased.”
