In John 15:14 Jesus says: “You are My friends if you do what I command you.” And then later on in the great commission, He gives the following instruction to His disciples before He ascends into heaven:
“And Jesus came up and spoke to them, saying, “All authority has been given to Me in heaven and on earth. Go therefore and make disciples of all the nations, baptising them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age.” Matthew 28:18-20 NASB
Jesus didn’t give this command casually. He always modelled for us how we should walk, before asking us to do the same. Jesus Himself was baptised by John the Baptist and it was only then that the Holy Spirit descended on Him so that He could begin His earthly ministry.
So clearly being baptised is something we should do. But what is it? Who can get baptised? How does the whole thing work?
