Be on your guard; stand firm in the faith; Be men of courage; Be strong! ( 1Cor 16:13)
This is military language. The writer is not giving a suggestion of what they should do; He is giving a command. He is encouraging them to act appropriately as mature and brave believers.
All believers should be strong in their faith as they face both internal and external challenges. They should ” be like a tree planted by the waters , which spreads out it’s roots by the river, and will not fear when the heat comes; but her leaf will be green, and will not be anxious in the year of drought, nor cease from yielding fruits ( Ps 1:3)
