NOTE: This post was written in response to the previous post about whether or not the Father turned His face away from Jesus on the Cross.
I now realize, that there are many other ideas for why Christ had to die. There are two that are compelling to me, and I take them both seriously:
1. He died to show us how to live. Christ's entire life was meant to be something we followed. He was not interested in controlling people's moral actions, instead every action was meant as a means of self-sacrifice so that others may have life and have it more abundantly – right here, right now on Earth – not just in a reward in the afterlife.
His resurrection was then a reminder that even in death, it isn't an end to us, but that God has power over life and death and there is more for us. Death isn't an end, but only a beginning and so giving it up for another isn't a terrible end to life, but a beautiful beginning.
2.He died because we required a sacrifice. The view that resonates the most with me however is that Christ's death wasn't because God could not bear to look at sin and required death and blood to overcome his aversion to it, but that we could not look at sin without requiring blood and vengeance. The entire sacrificial system was simply man's best effort at serving a loving, Holy God in light of our own understanding of intrinsic evil in and amongst us.
God however has always loved us, always called us towards a more beautiful, peaceful life by overcoming that evil around us rather than having it control us. God has never required a sacrifice for His love, we simply assumed He did.
To me that makes His death even more beautiful.
Those two ideas have radically changed the way I interact with the world around me in light of Christ's life, and I'll never go back to where I was before.
