6:2 are dead to sin. This should be read “have died to sin.” There are eight references to the believer’s death in Christ, in Romans 6:1-11, and all are stated in a tense that speaks of action completed in the past. That is, since our sins were placed on Christ, and He paid the price of redemption by His death for those sins, we died with Him. We also live with Him in His resurrection, and our daily lives should reflect these great truths.
6:2 live any longer therein. One who has truly been redeemed by faith in Christ’s death for his sins may occasionally slip into a sin, but he cannot live therein!
