10 Finally, be strong in the Lord and in the strength of His might. 11 Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. 12 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 the heavenly places. Ephesians 6:10-12 (NASB)
In the passage above the words “Put on” translate the Greek verb ἐνδύσασθε (endysasthe) the second plural, aorist middle imperative case of ἐνδύω (endyō) which means “clothe.” This is a command for believers to clothe themselves with the “full armor of God” and never take it off. Why? The Church and God’s truth are continually under attack by our enemy. We ἐνδύσασθε this whole armor in order to stand firm in the evil day. Well, this is most definitely an evil day when truth is seen as something to be bargained away or shunned while lies and that which only appears to be the truth is elevated as if it is the truth. Therefore, we must become discerning and wise and that means we must consistently wear this armor.
