In conclusion, be strong in the Lord [be empowered through your union with Him]; draw your strength from Him [that strength which His boundless might provides].

Put on God’s whole armor [the armor of a heavy-armed soldier which God supplies], that you may be able successfully to stand up against [all] the strategies and the deceits of the devil.

For we are not wrestling with flesh and blood [contending only with physical opponents], but against the despotisms, against the powers, against [the master spirits who are] the world rulers of this present darkness, against the spirit forces of wickedness in the heavenly (supernatural) sphere.

Ephesians 6:10-12 (Amplified Bible)
