Have you ever tried to search the web on an old computer. It can be pretty annoying. Webpages half loaded. You know the look. Content illedgible. Boxes with little red x's litter the screen. The hour glass is laid out in the "infinity" position. It's stuck. You get frustrated. So maybe you wait (some can wait much longer than others) until you can take it no longer then you click refresh or renew. And if you're lucky the page displays, the content is ledgible, the hour glass disappears. Happy surfer.
People get stuck. Christians get stuck. Churches get stuck. Stale. Frustrating. Renewal is usually what's needed. But for renewal to happen the page has to be cleared. Yes, I know it's scary, but what other option do you have? Merely staring at 'stuck' doesn't 'unstuck' it.
That's what God was telling Israel through the prophet. You're stuck, time to refresh.
Habakkuk 3.2 Lord I have heard of your fame. I stand in awe of your deeds, O Lord. RENEW them in our day, in our time make them known; in wrath remember mercy."
