Living in a fallen world we all go through difficult times.  Living with wars, diseases, broken bodies and crushed hearts is not easy.  Peter says we as Christians are to feel unspeakable joy because Christ lives inside of us.  James says that we are to consider trials and tribulations pure joy.  Do we honestly feel joy all the time?  NO not always.  Paul wrestles with living in this fallen world and concludes that feeling unspeakable joy is possible but only by keeping your eyes fixed on the new heaven and new bodies we are about to receive.
