Baptism is an outward expression of and inward change. It's a public declaration of how Jesus changed your life. Being baptized shows others that you've decided to follow Jesus and allows them to celebrate this decision with you (Acts 16:31-34).
Baptism doesn't save a person; it's a symbol and celebration of salvation (1 Peter 3:21). The power that brought Jesus back to life is the same power Jesus uses to change our lives - and that's worth getting excited about!
