"Finally, be strong in the Lord and in the strength of His might. Put on the whole armor of God, so that you will be able to stand firm against the schemes of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in heavenly places.
Therefore, take up the full armor of God, so that you will be able to resist in the evil day, and having done everything, to stand firm. Stand firm, therefore, having girded your loins with truth, and having put on the breastplate of righteousness, and having shod your feet with the preparation of the Gospel of peace; in addition to all, taking up the shield of faith with which you will be able to extinguish all the flaming arrows of the evil one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God."
There is a mighty battle going on in life - one that we often aren't even quite aware of. If we want to be on the winning side we are going to need God's armor!
