We can still call on God for help in overcoming our enemies, whoever and whatever they may be. Enemies and temptations come in various forms. I noticed this year that several friends gave up Facebook for Lent. Others have told me, both men and women, that they have become addicted to pornography on the internet. Temptations abound.
But where temptations abound, grace can abound all the more. David never had to fight the internet, but he gave us an example in going out to face the enemy, calling on God at all times, and listening when God spoke. Following this model, we too can be people after God's own heart. We can be victorious; we can conquer our enemies and hold our ground.
Psalm 60:11-12 Give us aid against the enemy, for the help of man in worthless. With God we will gain the victory, and he will trample down our enemies.
