And we know that for those who love God all things work together for good, for those who are called according to his purpose. (ESV)
While this is a verse filled with infinite hope for every believer (only those who love God and are called according to his purpose can claim this promise), the questions often should be asked if we really believe this. How do we react when the small things, or big things, of life often jump up and interrupt our intended purposes and desires. Do we become angry and irritated or do we respond with faith based on the promise of this verse. Stuart Olyott has some great comments concerning this verse.
But why did he call? It is because he purposed to; all the reasons lie with him and none of them with me. And the same purpose is working itself out in every event. every circumstance, every joy, every setback and every detail of our lives. Big doors swing on small hinges, and even those small hinges are put in place by God's invisible hand. Everything is included - red traffic lights, unwelcome delays, bitter disappointments, family quarrels, terminal illnesses, unspeakable joys, and golden moments. Nothing is left out. I think that Romans 8:28 is one of the most comforting verses in the whole Bible. I don't know where I would be, or where you would be, if somebody took it out.
Indeed, every event down to a single atom is controlled by God according to His purposes. And for believers he promises that every event is for our good. Do we believe this? The next time things don't or perhaps they do work our the way you desire, remember that our Sovereign God still rules and reigns and He is purposing this event for our absolute best.
