2 Samuel 1: How the Mighty Have Fallen

"Your glory, O Israel, lies slain on your heights. How the mighty have fallen!
“Tell it not in Gath, proclaim it not in the streets of Ashkelon, lest the daughters of the Philistines be glad, lest the daughters of the uncircumcised rejoice.
"O mountains of Gilboa, may you have neither dew nor rain, nor fields that yield offerings of grain. For there the shield of the mighty was defiled, the shield of Saul—no longer rubbed with oil.
From the blood of the slain, from the flesh of the mighty, the bow of Jonathan did not turn back, the sword of Saul did not return unsatisfied.
“Saul and Jonathan—in life they were loved and gracious, and in death they were not parted. They were swifter than eagles, they were stronger than lions.
"O daughters of Israel, weep for Saul, who clothed you in scarlet and finery, who adorned your garments with ornaments of gold.
"How the mighty have fallen in battle! Jonathan lies slain on your heights.
I grieve for you, Jonathan my brother; you were very dear to me. Your love for me was wonderful, more wonderful than that of women.
"How the mighty have fallen! The weapons of war have perished!” - 2 Sam. 1:19:27 NIV

Where are the David's of today?  Where are the men who cry for those who have been destroyed, for those who have been brought down in defeat?  What kind of king would David have been if he did not grieve for Saul as he did?  Was his grieving a reflection of God's own heart?

We need to understand what it means to have the heart of God.  It means that rather than being ecstatic over our our enemy's defeat, we grieve for them.  It means we look at our enemies with God's eyes rather than our own.  It means, as Jesus said, that we love our enemies, that we do good to those that 'despitefully' use us.   "You have heard that it was said, ‘Love your neighbor and hate your enemy.’ But I tell you: Love your enemies and pray for those who persecute you, that you may be sons of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your brothers, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect. -Matt. 5:43-48 NIV

In order to be like our Father in heaven, we must have perfect love, love that casts out all fear.  Rather than gloating over the demise of our enemies, we should be grieving and crying as David did, 'How the mighty have fallen!'
