Ever since I can remember, I have prayed the following prayer every day: Lord right now I put on the full armor of God:
1) The Helmet of Salvation.
2) The Breast-Plate of Righteousness.
3) The Sword of the Spirit.
4) The Shield of Faith.
5) Loins Girded up with the Belt of Truth.
6) Feet Shod with the preparation of the Gospel of Peace.
7) The Garment of Praise for the Spirit of Heaviness.
8) Praying without Ceasing.
I encourage each one of you to spiritually put this armor on every day. It is essential to your survival. Remember that just because you have a sword in hand, does not mean that you know how to wield it. Satan is looking for any holes in your armor, so it must be a package deal. If you are feeling discouraged and depressed, put some worship music on to battle against that spirit of heaviness. If you are taking on fiery darts from the evil one, then grab your shield of faith. Etc...
I can tell you that praying this prayer daily will not just arm you. You must take the necessary means to accomplish this. There is no substitute for reading the Bible and having the Lord speak to you...
