What does Paul repeatedly say Christ's death means for believers?
Paul repeatedly teaches that Christ died for our sins, and that as He died, believers must die; out of that death they receive new life, eternal life. This new life is not limited to this earthly life of 70, 80, or 90 years but lasts forever, as Ephesians 2:1 describes being made alive.
Les explains that all through his epistles, Paul keeps hammering home that Christ died for our sins, and that as He died, we have to die—Ephesians 2, verse 1—and out of that death we get new life, eternal life. This life is not just for this life, for this 70, 80, 90 years, but forever. Les also points out that Paul writes only to believers, addressing the saints, every believer. In Ephesians 2:1, to us as believers, Paul writes that He has already made us alive, past tense, it is already done; “made alive” means exactly that.
And you hath he quickened, who were dead in trespasses and sins;
