I never liked mass punishment, but it is a proven behavior modification technique.
We who are without sin, must organize and give the sinners blanket parties just like Basic Training at Fort Polk. The needs of the many out weigh the whacks from soap bars in socks to the few.
God isn’t punishing us. However, He must show the reality of sin and the Plan of Salvation in all truth and glory, so every creation can see it for what it is, so that when sin is put to rest, it will never raise its ugly head again.
