1 Samuel 17:47New King James Version

⁴⁷ Then all this assembly shall know that the Lord does not save with sword and spear; for the battle is the Lord’s, and He will give you into our hands.”

After young David, the shepherd boy, convinced King Saul to let him go out and fight Goliath, the first thing the king did was dress David in his own armor and bronze helmet. But David said, “I cannot walk with these” (1 Samuel 17:39). So David went out to face Goliath with his own “armor”: a tunic, a staff, a sling, five stones, and faith. For that task, that was all David needed to defeat his enemy.

Psalm 44:4-8

When we face the giants that threaten us in our life, there is a temptation to put on “armor” God didn’t design for us to wear. It may be the armor of this world (position, power, education, wealth, influence) or it may be armor that we’ve seen a fellow Christian successfully wear. It may take a few battles for us to learn that God has provided all the armor we need: truth, righteousness, the Gospel, faith, salvation, Scripture, and prayer (Ephesians 6:14-18).
           

Face your giants today clothed in the armor of Christ. Let God prepare you for battle, and you will be victorious.

Our enemies are on every side, and so must our armor be.
