2 Timothy 4:5

But as for you, be clear-headed in every situation (stay calm and cool and steady), endure every hardship (without flinching), do the work of an evangelist, fulfill (the duties of) your ministry.

We live in trying times to discourage and oppress the believer and move them away from the faith.  As believers, we must not forget who we are in Christ as ambassadors for Him on this earth.  We have authority as believers, and the devil is afraid that we will use it.  We must stand up for ourselves and our faith.  Jesus stood up for us!
