It says "for if you do X then you shall be saved." Meaning, at the point you do X, you are saved, and not a moment before. Greek verb tenses are what tell us this, which are a bit more than "is," "was," "will be" etc for English.
If it said "for if you X, then you are saved," B57 would have a leg to stand on, because it could be interpreted that doing X is just an indicator that one is already saved.
Uh, no. Ordo Salutis (the logical order of salvation) is, when the message is preached, the sinner hears, then he believes, then he calls, and then he is saved. (Romans 10:13-14) Water baptism is a work. Paul teaches "not of works," but "by grace are you saved through faith."
Paul writes, comparing works (what Israel had to "DO" (including baptisms)) with faith:
For Moses writes about the righteousness which is of the law, “The man who does those things shall live by them.”But the righteousness of faith speaks in this way, “Do not say in your heart, ‘Who will ascend into heaven?’ ” (that is, to bring Christ down from above )or, “ ‘Who will descend into the abyss?’ ” (that is, to bring Christ up from the dead).But what does it say? “The word is near you, in your mouth and in your heart” (that is, the word of faith which we preach):that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.For the Scripture says, “Whoever believes on Him will not be put to shame.”For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him.For “whoever calls on the name of the Lord shall be saved.”How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher?And how shall they preach unless they are sent? As it is written: “How beautiful are the feet of those who preach the gospel of peace, Who bring glad tidings of good things!” - Romans 10:5-15

Do you see?
The righteousness which is of the law (doing good works to attain salvation (for under the law, faith was a required work)) is different than the righteousness which is of faith, in this way:
The righteousness which is of the law is achieved by the man who does things and lives by them. But the righteousness which is of faith is that one believes unto righteousness and makes confession unto salvation.
Not even the Baptists teach that calling is done at a water baptism. I know, because I used to be Baptist.
