There is a reason we are given the imagery of armor in preparation for the life before God in Ephesians 6. This imagery is used because our life is a fight. It is a constant fight against the things which keep us from getting to God. Closeness to God is our ultimate good as indicated in Psalm 73, but our life is always full of things which prevent us from that ultimate good of closeness. Those things never cease to present themselves each day. They must be fought and laid aside so we may continue to come closer to God.
This is why Ephesians 6 gives us a whole and complete armor for our daily fight. Every day we are to prayerfully and intentionally put on this armor that we might fight back all those things which prevent us from getting to God.
The life of the follower of Jesus is anything but lazy. The life after Jesus is a fight, and if we fight correctly each day it will only be done with the strength of Jesus Christ found in intentional prayer.
