Why should I be baptized?

In a few words, the believers must be baptized because Christ commands it!. Jesús said Matthew28 : 19-20

“Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you.”

Being baptized is following Jesus’s example! The Gospel according to Mark says:

Mark 9:1

“9 At that time Jesus came from Nazareth in Galilee and was baptized by John in the Jordan”
