This is how we should become accustomed to baptism and identity Christ as the one to serve:
¶ The next day John seeth Jesus coming unto him, and saith, Behold that Lamb of God, which taketh away the sin of the world. This is he of whom I said, After me cometh a man, which was before me: for he was better than I. And I knew him not: but because he should be declared to Israel, therefore am I come, baptizing with water.

Then Jesus came from Galilee to John at the Jordan [River], to be baptized by him. But John tried to prevent Him [vigorously protesting], saying, “It is I who need to be baptized by You, and do You come to me?” But Jesus replied to him, “Permit it just now; for this is the fitting way for us to fulfill all righteousness.” Then John permitted [it and baptized] Him. After Jesus was baptized, He came up immediately out of the water; and behold, the heavens were opened, and he (John) saw the Spirit of God descending as a dove and lighting on Him (Jesus), and behold, a voice from heaven said, “This is My beloved Son, in whom I am well-pleased and delighted!”

Know ye not, that all we which have been baptized into Jesus Christ, have been baptized into his death? We are buried then with him by baptism into his death, that like as Christ was raised up from the dead to the glory of the Father, so we also should walk in newness of life.

So we can now identify the reason for baptism is “fitting to fulfill all righteousness” as stated by Jesus.
And there is this:
For ye are all the sons of God by faith, in Christ Jesus. For all ye that are baptized into Christ, have put on Christ. There is neither Jew nor Grecian: there is neither bond nor free: there is neither male nor female: for ye are all one in Christ Jesus. And if ye be Christ’s, then are ye Abraham’s seed, and heirs by promise.

But put ye on the Lord JESUS CHRIST, and take no thought for the flesh, to fulfill the lust of it.

Beware lest there be any man that spoil you through philosophy, and vain deceit, through the traditions of men, according to the rudiments of the world, and not after Christ. For in him dwelleth all the fullness of the Godhead bodily. And ye are complete in him, which is the head of all principality and power. In that ye are buried with him through baptism, in whom ye are also raised up together through the faith of the operation of God, which raised him from the dead.

Let’s see how Jesus spoke of baptism:
¶ Then James and John the sons of Zebedee came unto him, saying, Master, we would that thou shouldest do for us that we desire. And he said unto them, What would ye I should do for you? And they said to him, Grant unto us, that we may sit, one at thy right hand, and the other at thy left hand in thy glory. But Jesus said unto them, Ye know not what ye ask. Can ye drink of the (Communion) cup that I shall drink of, and be baptized with the baptism that I shall be baptized with? And they said unto him, We can. But Jesus said unto them, Ye shall drink indeed of the cup that I shall drink of, and be baptized with the baptism wherewith I shall be baptized: But to sit at my right hand and at my left, is not mine to give, but it to them for whom it is prepared.

What is all of this for? It’s for us as the body to be joined with the Head of the body..to Christ Jesus.
In that ye are buried with him through baptism, in whom ye are also raised up together through the faith of the operation of God, which raised him from the dead. And you which were dead in sins, and in the uncircumcision of your flesh, hath he quickened together with him, forgiving you all your trespasses, And putting out the handwriting of ordinances that was against us, which was contrary to us, he even took it out of the way, and fastened it upon the cross, And hath spoiled the Principalities, and Powers, and hath made a show of them openly, and hath triumphed over them in the same cross. Let no man therefore condemn you in meat and drink, or in respect of an holy day, or of the new moon, or of the Sabbath days, Which are but a shadow of things to come: but the body is in Christ.
Let no man at his pleasure bear rule over you by humbleness of mind, and worshipping of Angels, advancing himself in those things which he never saw, rashly puffed up with his fleshly mind, Wherefore if ye be dead with Christ from the ordinances of the world, why, as though ye lived in the world, are ye burdened with traditions?

This leads to our understanding of our assignment after the baptism:
Go therefore, and teach all nations, baptizing them in the Name of the Father, and the Son, and the holy Ghost, Teaching them to observe all things, whatsoever I have commanded you: and lo, I am with you alway, until the end of the world, Amen.
