For us, it is nothing.
For we are born sinners.
But for the Son?
To experience being separated from the Father was an agony he never experienced ever before.
And, not only the separation.....
But to know, he was to be plunged into a gigantic septic tank filled with all the feces=sins of all mankind.
Being forced to taste it, filling his lungs, as he was to be drowned (die spiritually) on the Cross.
Imagine someone walking you over to a septic tank with ladle in hand, and force-feeding you it contents?
But we see Jesus, who was made a little lower than the angels
for the suffering of death, crowned with glory and honor; that
he by the grace of God should taste death for every man." Heb 2:9
Jesus was both horrified and absolutely repulsed by what He was shown that he was to go through to save us.
Sin to us sinners is,
"oh, so what?"
But to the pure Son of God?
To come in contact with sin would be a horror show.
When we sin, it is why the Holy Spirit must cease being one with us.
It is why we have 1 John 1:9, as God's provision to restore walking in the Light.
grace and peace .......
