As we walk in the world we must remember we're constantly dealing with spiritual wickedness. With that being said we are to put on the whole armor of The Most High. Having our loins girt with truth, the breastplate of righteousness, having our feet shod with the preparation of the gospel of peace, the helmet of salvation and the sword of the spirit. Prayer plays an important part of our walk as well.

Ephesians 6:10-20
