Ephesians 6:10-12 English Standard Version

10 Finally, be strong in the Lord and in the strength of his might. 11 Put on the whole armor of God, that you may be able to stand against the schemes of the devil. 12 For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places.

The world system will jam you up. The desire of satan is to keep Christians from standing for the truth in this evil age. As Christian men we need to have our foundation rooted to Christ.
