Therefore put on the full armor of God, so
that when the day of evil comes, you may be
able to stand your ground, and after you
have done everything, to stand.
Stand firm then, with the belt of truth
buckled around your waist, with the
breastplate of righteousness in place,
and with your feet fitted with the readiness
that comes from the gospel of peace.
In addition to all this, take up the shield
of faith, with which you can extinguish all
the flaming arrows of the evil one.
Take the helmet of salvation and the sword
of the Spirit, which is the word of God.
This is the second time Paul
tells the Ephesians to “take up” or “put on”
the whole armor of God. However, the first
time they were not fully aware of its
importance. After giving a powerful
description of the enemy, he says, “take up
the whole armor of God, that you may be able
to withstand in the evil day.” Soldiers do
not do battle every day, but the day of
battle is the day of testing. A soldier who,
on the day of battle, had not “taken up” his
full armor, would be unprepared to stand
against and prevail over the enemy.
Consequently, the “evil day” under
discussion in this verse is the day of
severe trial or testing, the critical
moments in our lives when the devil and his
sinister horde assault us fiercely. Seeing
as one never knows when these crises will
occur, one needs to be ready always. When
the Christian makes all the preparations God
has specified, then he will be able to
“stand” and prevail against him, for the
Bible tells us that if we resist Satan, he
will flee from us (James 4:7).
