God is developing us to respond to Him joyfully in the pressures of life and warfare. What if peace is the biggest pressure you can ever have? What if joy is an enormous pressure that God wants you to have? What if He wants you to be under the pressure of being happy? He is making us in His image, right? He lives in everlasting joy, so what if He is teaching you to laugh like He laughs? It’s in the Bible! He lives in everlasting joy. Joy is who He is. Rejoicing should be our response to who He is.
