Finally, be strong in the Lord and in his mighty power. Put on the full armor of God, so that you can take your stand against the devil’s schemes.
Goliath had shouted insults at Saul’s army for forty days. When David showed up and found out what had been going on, he was infuriated. How dare anyone speak like that about God and his people. When David was given permission to begin his battle with Goliath, it took very little time to successfully complete his mission. The battle was over in no time. The fat lady was clearing her throat when David stepped out onto the battlefield.
He knew the battle wasn’t really against Goliath, but against what Goliath stood for. According to Ephesians 6:12, “For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.”
He knew that not one man in Saul’s army would be able to beat Goliath in a flesh against flesh battle, but that didn’t mean they couldn’t win. They had to look to the one who was in charge of the battle for their plan of attack. Not Saul, but God.
David won his battle against Goliath because he was comfortable knowing his armor was God. He’d worn that armor before and knew how it felt. There is freedom and security in a good relationship with God. David was certain he’d be protected.
When God is your armor, you can relax and simply obey. No need to worry about the insults or threats against you. If you are obeying God and wrapped up in him, he is able to clear the path to your victory.
