What is baptism?
Quick answer
Baptism is a public sign of belonging to Jesus — symbolizing being washed from sin and united to Christ in his death and resurrection. It is an outward expression of an inward faith, commanded by Jesus for his followers.
Jesus told his disciples to make followers and baptize them (Matthew 28:19). From the start, baptism marked entry into the community of believers.
The act pictures the gospel: going under the water represents dying to the old life and rising to new life in Christ.
Christians differ on some details, but agree that baptism is an important step of obedience and public identification with Jesus.
