Why Should I Be Baptized? | Mt. 28:19-20

one of the sad realities of church history is that a subject that should be a unifying one for believers is actually a dividing one. Paul told us in Ephesians 4:5 that there is “one faith, one Lord, and one baptism.” Yet we find ourselves and many godly believers differing on many aspects of “one baptism.” Lutherans, Episcopalians, the Orthodox churches, and the Roman Catholic church all hold to the view that baptism effects the new birth. Since they all administer baptism to infants, they believe that when they sprinkle the water on a baby, that child is then regenerated.

Most of your reformed church and presbyterian churches also baptize infants, but they deny that baptism gives regeneration on those baptized. However, you really have to read their statement of faith carefully to come to that conclusion. Let me read for you what The Westminster Confession of Faith says “Baptism is a sacrament of the new testament, ordained by Jesus Christ, not only for the solemn admission of the party baptized into the visible Church; but also, to be unto him a sign and seal of the covenant of grace, of his ingrafting into Christ, of regeneration, of remission of sins, and of his giving up unto God, through Jesus Christ, to walk in newness of life.”So the teaching is that the sign and seal are only confirmed when the baptized infant later comes to faith in Christ.

Now the 1689 Baptist COnession of Faith uses the language of the Westminster Confession it says
Baptism … is intended to be, to the person baptized, a sign of his fellowship with Christ in His death and resurrection, and of his being engrafted into Christ, and of the remission of sins. It also indicates that the baptized person has given himself up to God, through Jesus Christ, so that he may live and conduct himself “in newness of life.”
rather than baptizing infants, it adds this “The only persons who can rightly submit themselves to this ordinance are those who actually profess repentance towards God and faith in our Lord Jesus Christ, being willing to yield obedience to Him.” Now, of course, I believe this line up with scripture this is, of course, is why I am a Baptist.

So this message in a sentence is this baptism is a confession of our faith in Jesus Christ and is done in obedience to His commands.
I am going to set out to make three statements concerning baptism and then prove them biblically.
