"Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; And your feet shod with the preparation of the gospel of peace; Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God." (Ephesians 6:13-17)
The Bible teaches that as believers, you and I are to occupy until Jesus comes. Occupy is a military term meaning to hold possession, or control, of conquered troops and territory. If we're to do that effectively, most of us are going to have to change our attitudes. We're going to have to recognize that Jesus has already won the victory.
That's right. Satan is already defeated. He was whipped at Calvary. We're not on the defensive, he is!
What's more, Jesus has given you His very own armor and sword to use to keep that defeated devil in line. You may be a 90-pound weakling on your own, but if you'll put on God's armor, the devil will never know it. He'll run from you just like you were Jesus.
Think about it. What would you do if you were the devil and you came face-to-face with some fellow wearing God's armor and God's helmet with God's weapons in each hand? As long as that fellow only spoke God's words, you would think that must be God inside there!
Don't neglect any of the armor you've been given. Wear it all. Keep the devil on the defensive--and occupy till Jesus comes.
