the 2 pillars of christian combat = spiritual warfare?

10Finally, be strong in the Lord and in his mighty power. 11Put on the full armor of God so that you can take your stand against the devil's schemes.

our opposition is not flesh and blood
spiritual things live for eternity
we have to believe spiritual things are more real than material things.

how do we be strong in the lord, and how to avoid things that will take strength away from the lord?

we're seated in heavenly places with Jesus.
thats our standing.
