Baptism Sunday!
Jesus was baptized by John the Baptist. It represents the old life being washed away, and the new life under and fully submitted to Christ. If it was important to Jesus to be symbolically cleansed of his sins, then it should be an example we should follow.
Publicly profess your faith. Being baptized is a great way to share your faith in Jesus with others. Jesus was baptized in front of a crowd, so typically, baptism follows this.
Celebrate the good work He has done. Baptism is also a great way to celebrate! This is a joyful occasion. A time to let go of your old self and being fresh. Your sins are ashes away and your new life begins.
