To answer that, I sincerely believe that along with things we can understand, this
also has more to it than we can entirely understand, even this way --
“For my thoughts are not your thoughts,
neither are your ways my ways,”
declares the Lord.
9“As the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts than your thoughts.
Isaiah 55 NIV
So, we cannot, literally cannot, fully understand the mind of God, but only know the partial things He has chosen to reveal to us.
Therefore, I think the atonement in the cross has more to it than anyone of us can say, or that perhaps if someone could say more, that we could not necessarily understand it all individually. Instead we can only have partial understanding at most. As I see it, many of the main theories of atonement have some truths in them. For example, Christus Victor has the truths we can also learn in the first passage (verses 1-14) of
Romans 6 NIV
But, these truths are not the entirety.
So, also for my own sense of the Influence theory of Atonement, which I've not found fully stated somewhere (though perhaps it is). To me, it means that if we can realize the reality of Christ on the cross this...
destroys our hatred for one another and for God.
So, I think there is more than one thing, and also additionally there is '
mystery' in the sense of being above our understanding, both.
