Baptism is immersion in water for the forgiveness of sins, as per the examples of the book of Acts. :thumb:
It is necessary for all
Matthew 28:19-20 - Go therefore 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 that I have commanded you. And remember, I am with you always, to the end of the age."
It is also symbolic
Romans 6:16-18 - Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness? But thanks be to God that you, having once been slaves of sin, have become obedient from the heart to the form of teaching to which you were entrusted, and that you, having been set free from sin, have become slaves of righteousness.
“The teaching” was the gospel, the death, burial & resurrection of Christ.
I Corinthians 15:1-5 - Now I would remind you, brothers and sisters, of the good news that I proclaimed to you, which you in turn received, in which also you stand, through which also you are being saved, if you hold firmly to the message that I proclaimed to you--unless you have come to believe in vain. For I handed on to you as of first importance what I in turn had received: that Christ died for our sins in accordance with the scriptures, and that he was buried, and that he was raised on the third day in accordance with the scriptures, and that he appeared to Cephas, then to the twelve.
“Obedience” to Jesus’ command for all to be baptized in the great commission and obedience to “the form of teaching,” is seen to be one and the same thing.
Romans 6:3-7 - Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? Therefore we have been buried with him by baptism into death, so that, just as Christ was raised from the dead by the glory of the Father, so we too might walk in newness of life. For if we have been united with him in a death like his, we will certainly be united with him in a resurrection like his. We know that our old self was crucified with him so that the body of sin might be destroyed, and we might no longer be enslaved to sin. For whoever has died is freed from sin.
It absolutely washes away our sins
Acts 22:16 - And now why do you delay? Get up, be baptized, and have your sins washed away, calling on his name.'
