There are so many different opinions, theories, and philosophies about baptism it is ridiculous! But just go back to the beginning.
Mark 16:16 - he that believeth and is baptized shall

And what matters is a clear conscience before GOD
I understand
And what matters is a clear conscience before GOD
be saved, he that beliveth not shall be damned. There are two very simple recipies here - if you want to bake a "saved cake" add together belief and baptism. If you want to bake a "damned cake" just use one single ingredient. So what kind of cake do you get if you only use belief but not baptism??? Mark 16 doesn't address that, but I will reiterate to get a "saved cake" it takes two ingredients belief
AND baptism.
Now in Acts 2 - Peter tells the people that baptism in the name of Jesus Christ is essential for them to be saved, and then only them that glady received his word were baptized.
In Acts 8 - Philip preaches to the city of Samaria and when they believe they are baptized.
Also in Acts 8 - Philip preaches to the Ethipian Eunuch and after the eunuch had already declared that Jesus Christ is the Son of God, he still needed to be baptized.
In Acts 9 - after Annanias lays hands on Paul and restores his sight Paul is baptized and begins learning of Christ.
In Acts 10 - Peter teaches the house of Cornelious (gentiles) and while he is teaching the Holy Ghost falls on them. And yet even after the Holy Spirit of God has fallen on them Peter commands them to be baptized in water.
In Acts 16 - When Lydia believe Paul's teaching and attended to the things he had taught she was baptized along with all of her house.
Also in Acts 16 - When Paul and Silas are freed from thier shackles in prison they witness to the jail keeper and when he requests what he must do to be saved, They tell him to believe on Jesus, and within that same hour he takes them to his home helps clean them up and is baptized along with the rest of his house.
In Acts 18 - Paul teaches in he synagogue in Corinith and persuades Crispus the chief ruler of the synagogue to believe and Crispus and many of the Corinthians believe and are baptized.
In Acts 19 - Paul finds believers who have only heard of John the Baptists baptism. Upon teaching them and confirming their belief he does two things, he baptizes them, and then he lays his hands on them and they receive the Holy Ghost.
In Acts 22 - When Paul is recounting his conversion unto the Jews of Jerusalem he tells them that Annanias commanded him to be baptized to wash away his sins.
All of these are the first examples of the church, and in each case baptism is a necessary requirement. In each case the individuals beleive first. Sometimes they receive the Holy Ghost before baptism sometimes they receive it afterwards, but in each case the believe, they are baptized, and they receive the Holy Ghost.
