I read that every morning in Africa a gazelle awakes knowing it must run faster than the fastest lion or will be killed. 
And every morning a lion awakes knowing it must run faster that the slowest gazelle or it will starve to death.
Whether a gazelle or a lion, when the sun comes up, it’d better be running!
We can learn a lesson from the gazelle and the lion – if you are not running to the Lord, the devil is stalking you. 1 Peter 5:8 says, “Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour.”
So what are we to do when the devil is stalking us? Again, Peter tells us. “Resist him; stand firm in your faith.” James puts it this way, “Submit yourselves therefore, to God. Resist the devil, and he will flee from you.” Paul states it plainly, “Do not give the devil an opportunity.” What is our best defense against the devil? Putting on the whole armor of God works!
Ephesians 6:13 says, “Therefore, take up the full armor of God, that you may be able to resist in the evil day. Above all, “Take up the shield of faith with which you will be able to quench all the fiery darts of the wicked ones.”
What is the full armor of God? It’s the Belt of Truth buckled around your waist; the Breastplate of Righteousness over your heart; feet fitted with the readiness that comes from the Gospel of Peace; the Shield of Faith used to extinguish all the flaming arrows of the evil one; the Helmet of salvation that protects your mind; and the Sword of the Spirit which is the Word of God. Clearly, our armor is designed for spiritual battle with the devil. Indeed, tangible weapons would not be effective against the devil’s tactics.
Weapons of Defense –
The first piece of armor is the belt of truth. Since the devil is said to be the ‘father of lies,’ TRUTH sets us apart as mutual enemies. The breastplate of RIGHTEOUSNESS is to guard our hearts with the righteousness of Christ given by God and received by faith. Feet fitted with the readiness that comes from the GOSPEL OF PEACE calls believers to advance into enemy territory in order to bring the message of peace to those who have not heard. The SHIELD OF FAITH is like a golden shield, solid, and substantial in warfare. The HELMET OF SALVATION preserves our minds from receiving false doctrine or to give way to the devil’s temptations.
The SWORD OF THE SPIRIT is the Word of God and is the only offensive weapon in the armor of God, and it speaks to the holiness and power of God’s Word. Reminder: Keep your weapons wrapped in prayer. God has given us these weapons to use against the devil, the evil one who prowls around like a roaring lion looking for someone to devour. Be alert!
