We are baptizing this Sunday! That always gets me excited. Baptism is the public display of the new birth we experience in Christ when we place our trust in him. It is also the entry point into the church. At baptism, we public confess Christ, and we public join the Church--the Body of Christ. Here are a couple videos from the Gospel Coalition about baptism:
