2 Samuel 8:2
“Then he defeated Moab. Forcing them down to the ground, he measured them off with a line. With two lines he measured off those to be put to death, and with one full line those to be kept alive. So the Moabites became David’s servants, and brought tribute.”
During the reign of Saul, Israel faced constant attack from within and without. From within, they faced uprisings from the Philistines; while beyond their borders, they were threatened by Moab, Ammon, and Syria. Saul’s foreign policy was to react to attacks as they came; once an enemy showed signs of attacking the armies of Israel, they would respond. David had a different approach. He decided to go on the offensive and remove the threats once and for all, even drawing a line in the sand to make his stance very clear.
David’s model serves as a good example for how the Christian should approach sin. Instead of allowing compromise to exist, and only dealing with personal sin when it begins to overtake us, we should take an offensive approach, seeking to remove all areas of compromise from our lives. Taking inventory of our private life and our homes is a great way to get this started. If you have allowed things in your life that may lead to sin, then it is time for a good old fashion spring cleaning. Maybe it is time to go through the fridge, CD collection, and computer, and toss some things out.
In this case, the best defense is a good offense.
