До римлян 6:3

Know ye not, that so many of us as were baptized into Jesus Christ--compare Co1 10:2. were baptized into his death?--sealed with the seal of heaven, and as it were formally entered and articled, to all the benefits and all the obligations of Christian discipleship in general, and of His death in particular. And since He was "made sin" and "a curse for us" (Co2 5:21; Gal 5:13), "bearing our sins in His own body on the tree," and "rising again for our justification" (Rom 4:25; Pe1 2:24), our whole sinful case and condition, thus taken up into His Person, has been brought to an end in His death. Whoso, then, has been baptized into Christ's death has formally surrendered the whole state and life of sin, as in Christ a dead thing. He has sealed himself to be not only "the righteousness of God in Him," but "a new creature"; and as he cannot be in Christ to the one effect and not to the other, for they are one thing, he has bidden farewell, by baptism into Christ's death, to his entire connection with sin. "How," then, "can he live any longer therein?" The two things are as contradictory in the fact as they are in the terms.

The apostle having at large asserted, opened, and proved, the great doctrine of justification by faith, for fear lest any should suck poison out of that sweet flower, and turn that grace of God into wantonness and licentiousness, he, with a like zeal, copiousness of expression, and cogency of argument, presses the absolute necessity of sanctification and a holy life, as the inseparable fruit and companion of justification; for, wherever Jesus Christ is made of God unto any soul righteousness, he is made of God unto that soul sanctification, Co1 1:30. The water and the blood came streaming together out of the pierced side of the dying Jesus. And what God hath thus joined together let not us dare to put asunder.

6:3 Baptism is the rite of initiation into the Christian faith (see Acts 2:38, 41). It sometimes symbolizes the entire conversion experience, so Paul refers to baptism as the means through which believers are joined to Christ in his death and resurrection (see also Rom 6:4). However, baptism has no value apart from faith.
