Do you remember the old videos that showed the atom bomb exploding just outside the schoolroom window? What were the children inside supposed to do in such an event? Duck and cover. That will fix everything.
Jesus tells us to do the opposite. When there is distress throughout the cosmos, to the extent that the sun, moon, and stars are disrupted by events, and there is distress of nations along with the roaring of sea and waves, as people faint with fear, what are we to do?
Duck and cover?
Absolutely not.
Jesus tells us that cosmic disruption isn't a reason to fear. In the midst of chaos, Jesus is still on the throne. Christ is still King. You need not fear -- despite what may be churning outside, God is alive and on the move, so be bold and proclaim your eternal hope in Jesus, our Lord and Savior, who will walk through the valley of the shadow of death along with us, and through him, we will endure!
