What has God done for believers who were dead in sins?
God has made believers alive together with Christ, quickening them despite being dead in sins. Because Christ died and rose, they died and rose with Him, and God has forgiven every trespass—past, present, and future—so their sins are already forgiven, not partly but completely.
Les explains from Colossians 2 that Paul writes to those who were dead in their sins—our pre-salvation existence—and in the uncircumcision of the flesh, which refers to pagan Gentiles. God has quickened believers together with Christ: when Christ died, they died; when He arose from the dead, they arose to newness of life. God made them alive together with Him, having forgiven every trespass—every last one they did commit, are committing, and will commit. They are already forgiven. Les stresses that when Christ died, He died for all the world’s sins, tasting death for every man; this forgiveness is now and forever.
And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
