Because you want to follow Christ’s example.
“At that time Jesus came from Nazareth in Galilee and was baptized by John in the Jordan.
(Mark 1:9)

Because Christ commanded it.
“Jesus said, ‘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.
(Matthew 28:19-20)

Because it shows you are a believer.
“Many of the Corinthians who heard him believed and were baptized.”
(Acts 18:8)

Because obeying Christ’s command shows you know Him.
“We know that we have come to know him if we obey his commands.
(1 John 2:3)


Baptism is a declaration.  It is declaring publicly that your life has been changed by Jesus.   When you go public with your faith through baptism, you are putting the gospel on display for all to see and hear.  You are saying Jesus is your Savior, your old life as a slave to sin is dead and buried (as Christ was dead and buried), and now you are living the new life that He has made possible.  The Bible puts it pretty simply... It is no longer you who live, but Christ living through you.

It is a symbol of Christ’s death, burial, and resurrection.
“Christ died for our sins ...He was buried  ...He was raised on the third day.
(1 Corinthians 15:3-4)

It is a symbol of your new life as a Christian.
“Therefore if anyone is in Christ, he is a new creation; the old has gone; the new has come!”
(2 Corinthians 5:17)
“We were therefore buried with Him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.
(Romans 6:4)

Baptism does not make you a believer; it shows that you already are one! 

Baptism does not “save” you; only your faith in Christ does that.  Baptism is like a wedding ring - it is the outward symbol of the commitment you have made in your heart.

“For it is by grace you have been saved, through faith - and this is not from yourselves, it is the gift of God - not by works, so that no one can boast.”
(Ephesians 2:8-9)
