He knows there will be pain on the other side.
Those who suffer for others' sins merely do it on this side.
Those who do not will suffer their sins elsewhere.
Everything comes from the Lord, he dispenses sin and redemption.
"You want to do sin?" says the Lord, "I'll hold your hand while you do it".
Nobody escapes pain however, it is the only way to Understand.
You will know it is for the best when you will have eyes that can See.
