Why Be Baptized?

Jesus set the example:
“At that time Jesus came from Nazareth and was baptized by John in the river.” Mark 1:9

Jesus commands it:
“Go and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit.” Matthew 28:19

It proves we are His:
“We know that we have come to know Him, if we obey His commands.” I John 2:3
