Water Baptism in the Scriptures my friend is an act of obedience
Offer Scripture in support of that position.
and is not required for salvation.
"Required" is your word, not mine. Scripture however does say, explicitly and unambiguously, that baptism is salvific, 1 Peter 3:21.
Allow me to ask you a question. If you and I went to a hospital and there we shared the gospel with a man who was lost and through the grace of God and the conviction of the Holy Spirit that man accepted Jesus and was saved.
No one accepts Jesus. Salvation is by grace alone through faith, which is the gift of God, not of ourselves, not by our works (Ephesians 2:8-9). But that issue aside, let's continue with the scenario:
Now later night as we were filling the swimming pool with water, he in fact died. Did he go to heaven or or not?
The Church already has a term for this: Baptism of desire. Which is why the Christian Church, historically, understands that Baptism is not "required" for salvation, but it is nevertheless the normative means through which a person becomes a Christian on account of what Scripture unambiguously teaches on the matter. So yes, should a person die before receiving Holy Baptism they will not be rejected by God:
Because Baptism isn't a matter of Law, but Gospel. And since salvation is a matter of God's grace, then it isn't about us checking off a list of things "required" for salvation; it is instead about the means by which God appropriates the salvation which is in Christ to us, which is through Word and Sacrament. Since Baptism is not a work of law or obedience, but an act of grace through which Christ "cleanses [us] with the washing of water by the word" (Ephesians 5:26) then the issue is not us accomplishing a thing, but rather confessing where God promises to act and confessing the grace and trustworthiness of God and His promises which are for us.
Because the one who hears the Gospel and believes has, indeed, true faith, we are therefore confident that God, in keeping His word to us, is faithful and true: That faith comes by hearing, and hearing by the word of Christ (Romans 10:17), and whoever believes on the Lord Jesus shall be saved (Acts 16:31, Romans 10:13)--but again, this is not of ourselves, this is the grace of God by which He grants us faith.
The fundamental problem here is wanting to turn salvation into a formula which one must get their i's dotted and t's crossed. That's not what salvation is; salvation is the good and gracious God rescuing the world through His Son, Jesus Christ our Lord. Taking hold of us sinners, adopting us as children, making us heirs, and declaring us His own both now and on the Future Day.
By speaking of "requirements" that's what one does, one turns salvation into a formula of human efforts and works, instead of the gracious activity of God rescuing us through the sufficient work of Jesus. The preaching of the Gospel, the administration of the Sacraments are not "requirements" which check the right boxes, they are the gracious means God uses to appropriate to us the gracious and saving work of God in Jesus for us. This is my chief problem with Evangelicalism and modern Protestantism on the whole; it uses the language of salvation by grace, but denies it by turning salvation by grace through faith into a salvation of human efforts and works by denying the all-sufficiency of God's mercy and love in Christ for us into a systematic salvation of human efforts. In this modern Protestantism has denied the central dogma of the Reformation: That salvation is by grace alone through faith on Christ's account alone, entirely apart from ourselves, it is God's work alone.
