RE: "The very purpose of Christ’s death is to win mercy for sinners."

Amen! And what is the purpose of winning mercy for sinners?

— "For freedom Christ has set us free" (Gal. 5:1 ESV).

— that we “might walk in newness of life … dead to sin and alive to God in Christ Jesus” (Romans 6:5,11 ESV).

— “that my joy may be in you, and that your joy may be full” (John 15:11 ESV).

— “for good works, which God prepared beforehand, that we should walk in them” (Eph. 2:10 ESV).

— that the “Father is glorified [as we] bear much fruit” (John 15:8 ESV).

— “to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works” (Titus 2:14 ESV).

— “that those who live might no longer live for themselves but for him who for their sake died and was raised” (2 Cor 5:15 ESV).

— “that you may proclaim the excellencies of him who called you out of darkness into his marvelous light” (1 Peter 2:9 ESV).
