Age of indifference?

Jeff Weddle writes on those who call the present day the "age of grace" and seem to think God no longer punishes sin as in OT times:

We take this to mean that God isn’t bugged by sin as much anymore. Things changed after the cross. “Before the cross sin was punished; after the cross God doesn’t punish sin because Christ took the punishment,” so goes the argument. So we have the notion that we’re “getting away with sin” due to Christ’s intercession. Thus, we are in “the age of grace.”

Allow me to present an argument against this label.

God’s opinion of sin has not changed since the cross. God does not abhor sin less because of the cross. Nor has His mind changed on whether sin needs judging. Rather than showing grace by “letting us get away with sin,” God is showing that He is fed up with humanity.

Ouch.
