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. 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. Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand (Ephesians 6:10-13).
I do not dress in a suit of armor. In fact, I do not even own one. The reason is that I am not expecting to need it. Unless you are in the military or are a police officer, chances are you don’t either. The only reason to wear armor is to protect you from an attack. You wear armor when you are planning to go into a dangerous place where you have good reason to expect that you may be attacked by an enemy.
Paul says that for us to be strong in the Lord we need to put on the full armor of God. Why? Because we need to ready to defend ourselves against the devil’s attacks. The devil is defeated but he is still an enemy. Despite the fact that he was decisively defeated at the cross, he is not giving up fighting against God and His Church. He is constantly scheming against God’s people. The word “struggle” is the Greek word for “wrestle.” He is not some distant foe, but is in close combat with us.
Paul says we should expect that the day of evil will come when we are spiritually attacked. If we plan to be able to stand or ground, we need to be prepared, wearing the full armor of God. Are you wearing your armor today?
