To be BAPTIZED IN WATER is a COMMAND, an ORDINANCE, a MANDATE of Jesus Christ to all those who believe in Him for salvation.
Jesus also commanded His disciples, as we read in Mark 16:15,16 ‘He said to them, “Go into all the world and preach the gospel to all creation. 16“He who has believed and has been baptized will be saved; but he who has disbelieved will be condemned.”’
You cannot baptize yourself. You have to be baptized by another follower of Jesus Christ. Jesus Christ showed us THE WAY. We have to follow His COMMANDS and follow His EXAMPLE, DO like He did and BE like He showed us to be. Jesus Christ was baptized by John the Baptist.
We read in Matthew 3:13 ‘“Then Jesus arrived from Galilee at the Jordan coming to John, to be baptized by him. 14But John tried to prevent Him, saying, “I have need to be baptized by You, and do You come to me?” 15But Jesus answering said to him, “Permit it at this time; for in this way it is fitting for us TO FULFILL ALL RIGHTEOUSNESS.” Then he permitted Him.’
The words of Jesus Christ are RIGHTEOUSNESS for those who OBEY Him. He JUSTIFIES those who OBEY His words. Those who disobey Him are already condemned.
The words of Jesus are not open for interpretation or modification. We either obey Him and do as he commanded or we reject Him and we perish. Salvation through Jesus Christ is for those who OBEY Him.
May Jesus bless you.
