You have a very circular reasoning here. But it is clear you are Church of Christ and outside mainstream Protestantism's belief in salvation by faith alone.
The scripture is clear here, Jesus could as easily said he who does not believe and be baptized is damed... but he did not.
The fact is that there are many many scriptures on salvation by faith and only a couple that speak of baptism says it all.
The God I worship does not need the works of men to forgive any one.. He said "it is finished" Not "it is finished for those that act correctly and are baptized"
I believe God acts on men to make them acceptable , not that man makes himself acceptable to God by ritual obedience .
Our baptism is a response to an inward change by God and our obedience to the great commission come from God. It is all God
