10In 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].
11Put 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.
(1) Your union with Him - we wrap ourselves in Him;
(2) Our ability to move (fight) in Him (our armor) is strength (kratos)
This is a way to be strong in the Lord.
KRATOS - is the Greek word for "strength". Kratos is His divine energy which allows us to Dominate in the spiritual world.
We DOMINATE because we are to be successful "against all the strategies and the deceits of the devil". With this spiritual body armor & strength, we can run our race!
