Read Proverbs 21:31  Today there are many tools that the army uses for war.  They have tanks and cannons.  The Air Force uses bombers and fighter airplanes.  The Navy uses battleships and missle launchers.  But back in Solomon's times they used horses and chariots for protection.  Our verse tells us that Solomon prepared for battle with his powerful horses.  In Psalms 20:7 Solomon's father, King David, said that "Some trust in chariots, and some in horses: but we will remember the name of the LORD our God."  Solomon must have heard his father say words like that because here in our verse Solomon wrote about where his true strength came from: true safety is only found in the Lord God.  David and Solomon prepared their horses and chariots in order to defend against their enemies, but then they prayed to God, who was their true source of safety.  God protected them.  And God protects us!  We may lock our doors at night, but only God can protect us from a thief breaking in.  We may lock our cars, but only God can keep our things safe from someone breaking into our car parked in a parking lot.  We may keep extra money in our purse or wallet in case of an emergency, but only God can protect us from someone stealing our purse or our wallet.  Just like Solomon, we try to plan for emergencies, but only the Lord can truly keep us safe.  We need to trust in God and not just in strong locks.
