13 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. 14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; (Ephesians 6:13–14)
I. THE NEED FOR THE ARMOR OF GOD
In verse 12, the need for the believer to be wearing spiritual armor was clearly described—our foes are not flesh and blood, but they are otherworldly demons directed by the cruel hate of the devil.
12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. (Ephesians 6:12)
In verse 13, Paul picks up on this and says…
Ephesians 6:13 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.
“Wherefore” means “therefore” or “for that reason.” Because you realize the grim power and abilities of your spiritual enemies, for that reason, you should put on the “whole armour of God.”
How can we, fallen, sinful human beings fight against the greatest sinner of them all, Satan? By putting on the armor of God.
This is God’s armor, as Isaiah describes—
17 For [the LORD, verse 15] put on righteousness as a breastplate, And an helmet of salvation upon his head; And he put on the garments of vengeance for clothing, And was clad with zeal as a cloke. (Isaiah 59:17)
What a blessing! The Lord shares his armor with the believer! You, Christian, are called to “take unto you” (ἀναλαμβάνω) the Lord’s armor. We will shortly see, piece by piece, how to do so.
But, first, the reason you’re to take this armor and put it on is so that you…“may be able to withstand”—When you are wearing God’s spiritual armor, you will be able to withstand the attacks of Satan.
You will be able to stand firm “in the evil day.” When is that day? Any day until Jesus returns has the potential to be an evil day. Satan may strike you at any moment.
Again, for emphasis, the verse says, “having done all to stand.” When all is said and done, the most important thing for the Christian to have done in this life-long battle is “to stand.”
That’s huge when you think about it—we are Christian soldiers who are engaged in a life-long spiritual battle. We must stand firm. How are we supposed to do that? How do we last for our entire life? By putting on God’s armor.
Let us look at this armor that God gives us to see what it is and how it can be put on. First, there is…
