Rom 6:1-4 What shall we say then? Shall we continue in sin, that grace may abound? 2 God forbid. How shall we, that are dead to sin, live any longer therein? 3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? 4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. You know what this means ? It means that those Christ died for cannot continue in the sin of unbelief ! To continue in unbelief is the same as to continue in sin, which quite frankly is an impossibility for any Christ died and rose again in behalf of, and heres why: You see, in the Judgment of God, all for whom He died and rose, died and rose together with Him, because He died in their stead and behalf, and consequently when He arose, they arose along with Him from the dead ; And correspondingly as He was raised from the dead [after dying because of their sins as their Legal Surety] by the Glory of the Father, even so they shall be also, in order to walk in the Newness of Life [by the Glory of the Father], which life is Spiritual and overcomes spiritual death ! This Newness of Life is that renewing of the Holy Ghost written of here Titus 3:5 5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost; And also what Peter says is being begotten again here 1 Pet 1:3 3 Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead, That word begotten again is the greek word anagennaō: to produce again, be born again, born anew metaph. to have one's mind changed so that he lives a new life and one conformed to the will of God To be Born anew or again, from above , This is what Paul means in Rom 6:4 4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. The we is everyone Christ died and rose again in behalf of , and that's why they cannot continue in sin and unbelief. See unbelief is the wage of sin, the fruit of death Rom 6:23 23For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord. Unbelief is the fruit of spiritual death !
