“We never know the wickedness of the human heart, however, until we stand before the cross of Calvary and watch man killing the Lord of Glory. The thought is overwhelming, breathtaking, unimaginable. God the Son comes to earth to rescue His creatures, and they turn on Him and kill the One on whom their very existence depends.
Of course, that was not the end. He rose from the dead and later ascended to heaven. Ever since then, He has been offering eternal life as a free gift to all who will repent of their sins and receive Him as Lord and Savior, believing that, as their Substitute, He died to pay the penalty of their sins.
That is what grace means. God could have turned His back on the human race. He could have vaporized them in a nuclear holocaust. No one would have been left to accuse Him of injustice. Instead, He chose to populate heaven with those who spat in His face and nailed Him to a cross.”
