Romans 8:2
For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
The word because (gar, “for”), connects through (lit., “in”) Christ Jesus in this verse with the identical phrase “in Christ Jesus” in verse 1. (In the Gr. word order of the sentence in v. 2, “in Christ Jesus” follows the law of the Spirit of life.) If 7:7-25 is Paul’s testimony of his struggle as a believer with indwelling sin, then “the Spirit of life” is the Holy Spirit of God, not the spirit of the new nature each believer receives. The Holy Spirit is the Member of the Godhead who regenerates every believing individual (Titus 3:5) and bestows new life (John 3:5-8), the resurrection life of Christ (Rom. 6:4, 8, 11). Romans 8:2 has the second mention of the Holy Spirit since 5:5, but He is mentioned 18 more times through 8:27. This law (“principle”; cf. 7:23) set me free (the Gr. aorist tense suggests a once-for-all act of freedom at salvation) from the law of sin and death. That principle is called the principle “of sin and death” because sin, as Paul said repeatedly, produces death (5:15, 17, 21; 6:16, 21, 23; 7:10-11, 13; 8:6, 10, 13). As the principle of sin it contrasts with the Spirit; as the principle that brings death it also contrasts with the Spirit who gives life. For the pronoun translated me some Greek manuscripts read “us” and others “you” (sing.). The difference is incidental; the truth stated applies to every believer.
