How much easier is it to be in a battle when you know what you’re up against?
David named Goliath’s weapons. He said “thou comest to me with a sword and with a spear”.
But even more important than knowing what you’re up against is knowing who is on your side.
David’s next statement: “but I come to thee in the name of The Lord.”
Yes, it benefits Christ’s followers to be able to recognize the schemes of the devil. To see temptation for what it is. But even more beneficial is to realize that we don’t have to fear the enemy’s attacks because we have the Eternal Champion, Jesus Christ, on our side.
So be aware of what is going on around you but also be confident that you don’t need to fall prey to it.
