Water baptism is a "work of righteousness." (Matthew 3:13-15; Titus 3:5)
In regards to Romans 6:3-4, as Greek scholar AT Robertson explains - Baptism is the
public proclamation of one's inward spiritual relation to Christ attained before the baptism. See on "Galatians 3:27" where it is like putting on an outward garment or uniform. Into his death (ei ton qanaton autou). So here "unto his death," "in relation to his death," which relation Paul proceeds to
explain by the symbolism of the ordinance. The
picture in baptism points two ways, backwards to Christ's death and burial and to our death to sin, forward to Christ's resurrection from the dead and to our new life pledged by the coming out of the watery grave to walk on the other side of the baptismal grave. There is the further
picture of our own resurrection from the grave.
It is a tragedy that Paul's majestic picture here has been so blurred by controversy that some refuse to see it. It should be said also that
a symbol is not the reality, but the picture of the reality.

Before mentioning baptism in chapter 6, Paul had repeatedly emphasized that
faith, not baptism is the instrumental cause of salvation/justification (Romans 1:16, 3:22-30; 4:4-6, 13; 5:1). That is when the old man was put to death and united in the likeness of His death, which water baptism
symbolizes and pictures. Righteousness is "imputed to us who believe in Him who raised up Jesus our Lord from the dead, who was delivered up because of our offenses, and was raised up because of our justification." (Romans 4:24,25)
Since believers receive the benefits of Christ’s death and resurrection (justification), and that through faith, believers must be spiritually united to Him (delivered and raised up with Him). If baptism is taken as the instrumental cause, then Paul contradicts what he had established before, namely that
justification is by faith, not baptism. *Hermeneutics. Paul clearly teaches that what is
signified in baptism (buried and raised with Christ) actually occurs "through faith." Christians are "buried with Him in baptism, in which you also were raised with Him through faith in the working of God, who raised Him from the dead" (Colossians 2:12). Justification on account of union in Christ's death, burial and resurrection is brought about "through faith" - and is properly
symbolized by dipping the new believer in and out of the water.
In regards to Ezekiel 36:26, Christian baptism is not done by sprinkling, but immersion. Try again. You would walk around mountains of grace in order to find water.
