Have nothing to do with godless myths and old wives tales; rather, train yourself to be godly. For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come.
1 Timothy 4:7-8
Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places.
Ephesians 6:11-12
