A third reason you need your armor is found in an interesting phrase in ( Ephesians 6:13 ). Paul says we need to stand firm and resist Satan in the evil day. What is the evil day? That’s the day when your number comes up, so to speak. One translation puts it, when things are at their worst. Are you having it pretty easy right now? Enjoy it, because an evil day is coming. That’s not pessimism, just reality. There are days when Satan is going to unleash the forces of hell on you. When those times come, you need to have your armor on. Ask job about the evil day, when Satan unleashes everything he has against you. Job couldn’t do anything about his horrible losses, but he stood firm by saying, Though He slay me, I will hope in him ( Job 13:15 ). You need the armor of God to stand firm when the evil day comes. in ( 1 Corinthians 16:13 ) Paul writes, stand firm in the faith. That’s the key. You can stand firm because your faith is in the one who provides you with the armor. He has surrounded you with protection, so you don’t worry about the enemy’s attacks. God wants us to hold our ground and not budge when the evil day comes.
