The gospel demonstrates the righteousness of God -- the equity, kindness, and impartiality of God. When we are redeemed and brought back you our created purpose, the goodness of God though us is put on display to the world. The restored marriage, a mended family, a captive set free, an infirm person healed...all these things testify of the love of God for mankind. We all were once destined to destruction and eternal separation from God, but when the kindness of God appeared in the person of Jesus Christ, salvation came to us all, proving to every principality and power and opponent of God, that no man is forgotten by God, no man is cast aside; no man is left without the opportunity to be delivered from the corruption of this present, evil world.
