The Bible gives us two perspectives on the crucifixion of Christ, and the two perspectives teach us two very different lessons.
From one perspective, the cross of Christ represents a divine transaction. The Son of God, in full agreement with his Father and out of love for his people, goes to the cross willingly, bearing human sin on his shoulders. He endures the just consequences of that sin, is punished in the place of those who will trust in him. He willingly surrenders his life, tasting death for others so that those others might live.
From this angle, I learn this: Christ bore the cross for me, so that I need never bear it. My sin is paid for, and there can be no wrath for me.
From another perspective, the cross of Christ represents a human injustice. The innocent Christ is flogged and tortured, accused falsely and strung up by sinful people. He suffers because of the envy and fear of the priestly caste, the pride of the civic leaders, and the cowardice of the Roman governor. He is hated because of what he represents: the righteousness of God in a world full of unrighteousness. And he is killed, ultimately, because people living in the darkness hate the light.
From this angle, I learn this: Christ bore the cross for me, so that I might understand that I also have to bear it. In this world, the Christian will look foolish and weak. The Christian will represent something that the world finds repellent. If we try to get away from that, we refuse to take up the cross, and thus we refuse to follow Christ.
