Yes I agree baptism is exactly about that but also look here this also is true and relates
“And ye are complete in him, which is the head of all principality and power: in whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ: buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead. And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;”
Colossians 2:10-13 KJV
look also here which adds more to the being raised up from the burial a new person in Christ
“For as many of you as have been baptized into Christ have put on Christ. There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus. And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.”
Galatians 3:27-29 KJV
there’s a lot of meaning to the doctrine in the Bible things like baptism are actions of faith . We get baptized because we believe the doctrine they preached about it like what Paul’s written in his letters such as these three examples
if we hear about it and then scoff and reject it as truth it’s never going to be of faith believing ……
a theres a lot to learn about things like baptism or other sinple basic things like communion ….in Paul’s letters
“For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread: and when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come. Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body. For this cause many are weak and sickly among you, and many sleep.”
1 Corinthians 11:23-30 KJV
If we never start believing what he’s taught about these subjects like baptism for remission of sins or communion with the body and blood of Christ we’ll never be acting in any faith when participating in them
Clearly there is deep meaning in baptism. And other doctrine like communion we see it’s even affected thier health and spiritual awareness
“he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body. For this cause many are weak and sickly among you, and many sleep.”
as often as we hear the truth and then reject it and refuse to believe what the words teaching us were rejecting the effectual power of Gods word to change us and redeem us from the grave we’re headed for without him
baptisms power is what it means according to Gods word as you have pointed out there it’s the same with all the doctrine …..
