Sin is a horrible destructive element mere words can barely explain. It is drastically different than the Holiness that the Trinity contain. We barely understand the holiness, the purity, the perfect Love, the wisdom, the mercy that is contained in God. God is perfectly just, there is not one speck of injustice in Him. And He loves us, creating us in His image. I don't know how He was able to endure Adam and Eve's sinning, knowing the destruction their choices would reap. But He also knew that it was the only path that would produce a free willed choosing by some, of God's Way in the end. The pain God must endure constantly watching His most loved creation destroy itself of its own free choice, must be unbearable on human standards.
And then to heap pain upon pain, God had to do the unbelievable, and contain Himself in human flesh IN ORDER TO SUFFER THE CONSEQUENCES of the sins brought upon humanity by Adam and Eve, and all those following who choose again and again to sin, turning from God and godly ways. By suffering the very presence of evil undeservedly, God was able to somehow make the sacrifice that would perfectly repel evil, that evil could not withstand, and then offer it to those willing to accept it. It was the first human's treacherous rebellion that brought sin into the rest of humanity and Christ’s perfect humanity that was able to repel it's consequences.
I sometimes wonder if we have the words to express what happened on the cross. Spiritually speaking it was likely something like the force of opposite magnetic poles. Evil and holiness cannot cohabit. It is not possible. They may stand near each other as they do in this world, but they cannot unite. When Christ somehow miraculously took upon Himself the heavy burdensome sin of humanity, for a moment He experienced the separation and cried out "Eloi, Eloi, lama sabachthani?"—which means, "My God, my God, why have you forsaken me?" I cannot conceive how that whole thing is possible either physically or spiritually. God is a lot more powerful than we give Him credit for I think. But that moment must have been a violent moment spiritually when taking upon Himself the full burden of sin, holiness HAD to depart. Evil and holiness cannot unite. And then it was done. Something else was created from that action. We call it a spiritual bridge, a way back to God. By accepting Christ’s sacrifice we can come into the presence of God and God can come unite within our very being. Now that really doesn’t follow known physical or spiritual ‘rules of creation’.
Even the rest of it is difficult to fully comprehend. I know one cannot kill God, so to me it makes sense that He resurrected Himself. Yet, it is still difficult to grasp that that moment now enables us to come to God and repent of our sin which Christ has now destroyed the power of over us. But we don't have to fully understand it to believe it and act upon it.
Father forgive us.
