One of the easiest arguments to prove in providing someone with salvation is the case for baptism, yet ironically, as I’ve stated in other articles, it is one of the most forgotten “traditions” of following Christ’s Grace.

The average believer with at least some knowledge of the Bible knows that the Old Testament was a type and shadow for the New Testament. Colossians 2 takes circumcision, an Old Testament practice that separated oneself as servants of God. We know through Genesis 17 that the Israelites had a broken heritage in God if they didn't circumcise their men. 

Old Testament Covenant with Abraham 

Genesis 17
1  Now when Abram was ninety-nine years old, the LORD appeared to Abram and said to him,

    “I am God Almighty;

    Walk before Me, and be blameless.

2 “I will establish My covenant between Me and you,

    And I will multiply you exceedingly.”

3  Abram fell on his face, and God talked with him, saying,

4“As for Me, behold, My covenant is with you,

    And you will be the father of a multitude of nations.

5“No longer shall your name be called Abram,

    But your name shall be Abraham;

    For I have made you the father of a multitude of nations.

6“I will make you exceedingly fruitful, and I will make nations of you, and kings will come forth from you. 7“I will establish My covenant between Me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you. 8“I will give to you and to your descendants after you, the land of your sojournings, all the land of Canaan, for an everlasting possession; and I will be their God.”

9  God said further to Abraham, “Now as for you, you shall keep My covenant, you and your descendants after you throughout their generations. 10“This is My covenant, which you shall keep, between Me and you and your descendants after you: every male among you shall be circumcised.11“And you shall be circumcised in the flesh of your foreskin, and it shall be the sign of the covenant between Me and you…. 14“But an uncircumcised male who is not circumcised in the flesh of his foreskin, that person shall be cut off from his people; he has broken My covenant.”

New Testament Covenant involving baptism = cutting off of the flesh

Colossians 2
8See to it that no one takes you captive through philosophy and empty deception, according to the tradition of men, according to the elementary principles of the world, rather than according to Christ. 9For in Him all the fullness of Deity dwells in bodily form, 10and in Him you have been made complete, and He is the head over all rule and authority; 11and in Him you were also circumcised with a circumcision made without hands, in the removal of the body of the flesh by the circumcision of Christ; 12having been buried with Him in baptism, in which you were also raised up with Him through faith in the working of God, who raised Him from the dead. 13When you were dead in your transgressions and the uncircumcision of your flesh, He made you alive together with Him, having forgiven us all our transgressions, 14having canceled out the certificate of debt consisting of decrees against us, which was hostile to us; and He has taken it out of the way, having nailed it to the cross.
