Consider the idea that "baptism does not save" and then look at what these verses says
1Peter 3:
"20 Long before, they had refused belief, hoping that God would be patient with them, in the days of Noe. That ark which Noe was then building, in which a few souls, eight in all, found refuge as they passed through the waves,✻
vv. 19-20: It is certain that this passage represents the holy patriarchs as living in a place of detention, neither heaven nor hell, till our Lord came (cf. Mt. 27.52, 53). It is not clear why the Apostle concentrates his attention on the contemporaries of Noe, or how those who had refused belief attained salvation afterwards; it seems best to suppose that they were incredulous while the ark was being built, and repented when it was too late to escape the Deluge. ‘Hoping that God would be patient with them’; in the Greek, apparently, ‘while God’s patience waited for them’. ‘As they passed through the waves’; some would translate ‘by means of water’, but this does not apply to the story in Genesis; Christian baptism typifies passing through the waters of death (cf. I Cor. 10.2).
21 was a type of the baptism which saves us now. Our baptism is not a putting away of outward defilement; it is the test which assures us of a good conscience before God, through the resurrection of Jesus Christ.✻
‘The test which assures us of a good conscience’; the Greek might also mean ‘the petition for a good conscience’."
and think about this belief "We are saved by faith alone" and then look at what this passage says
James 2:
"24 Do you see that a man is justified by means of works, and not by faith alone?"
Take some time to think about it. Your own most cherished beliefs are contradicted by at least one passage of scripture.
