Finally, draw your strength from the Lord and from his mighty power. Put on the armor of God so that you may be able to stand firm against the tactics of the devil. For our struggle is not with the flesh and blood but with the principalities, with the powers, with the world rulers of this present darkness, with the evil spirits in the heavens. Therefore, put on the armor of God, that you may be able to resist on the evil day and, having done everything, to hold your ground. So stand fast with your loins girded in truth, clothed with righteousness as a breastplate, and your feet shod in readiness for the gospel of peace. In all circumstances, hold faith as a shield, to quench all [the] flaming arrows of the evil one. And take the helmet of salvation and the sword of the Spirit, which is the word of God.
Each day we must renew ourselves to live in the light of Christ. Daily we must put on our armor of God, or rather, the armor that is God. We are never always in the light of God, but it is a constant battle to be in the light of Christ, to be part of the one body. For we are never fully saved until we fully accept Christ, accept our armor of God, as just that and to live by, to live with, and to live through that daily. Our focus shouldn't be muddled in sin, rather we should rise above it and use our faith as a shield to block all that is degrading of our relationship with Christ. Only when we accept the armor of God do we become part of that armor.
