For sin will have no dominion over you, since you are not under law but under grace.” –  Romans 6:14
Cheap grace is the deadly enemy of our Church. We are fighting today for costly grace. – Dietrich Bonhoeffer

Residual sin, old favorites, remain in the life of cheap grace long after the ugly sin has been jettisoned.  There is simply too much about residual sin we hate to surrender to the life of holiness, His way of being and doing.  And Grace easily mutates into cheap grace in the life of those unwilling to release residual sin into the badlands of a lifestyle left behind for the trek after the Serving King. 

True, residual sin no longer has a place of dominion in the life of those trekking after the Serving King; instead, residual sin is an invited guest, an old friend still welcomed to the table, even a place of honor for those still foolish enough to dine alongside old ways of being and doing.  Stripped of dominion, residual sin is content to dine at the table as an honored guest, a retired king satisfied with a new label:  old friend.

The foolish, not understanding the cost of cheap grace, delight in cheap grace, pleasantly shocked to discover the possibility of still dining with residual sin while trekking after the Serving King.  Cheap grace welcomes residual sin, not recognizing the deadly enemy for what it is, an expensive parasite sucking life out of its host, content to kill the host slowly and quietly.  So the old friend snuggles up for the days still ahead, cautiously nibbling just a bit here and there, never too much to alarm the life-giving host.

Costly Grace ushers in a new way of being and doing liberated from the dominions of old.  Sin in every form, even the old friend, is recognized, stripped of old and cherished privileges, abandoned to yesterday, no longer welcomed at the table of life. 

Costly Grace makes no room for residual sin.  Costly Grace drags the old friend to the door, tossing it to the street, no longer tolerated at the table of Grace.  Cheap Grace pleads for leniency for the old friend, but Costly Grace will show no compassion for the old friend, slamming the door as a final good-bye gesture to the old king. 

But the old king is patient, content to wait in the street until cheap grace returns to open the door to welcome old, familiar sin back into the warmth.  Costly Grace lingers, ever on watch, determined to keep old friends banished…

Things to consider...

Why is residual sin so patient in its assault on the inner being?

What is the ultimate cost of allowing residual sin to remain?
