Romans 8:28 is a very popular verse to quote—and misquote. It is often boiled down to a simple “God works all things for good”, but that is simply not what the text says. Paul himself qualifies “the good” that God works: it is for those “who love him” and “who have been called according to his purpose”.
Why does this matter? Why is this important? Because all things will not work together for my good unless I love God and I have been called according to his purpose. This is because, first and foremost, God works for his own good, for the good of Christ Jesus, and for his glory. And if we are in Christ, we are along for the ride! Things can go terribly bad, but if we are in Christ, everything will someday—sooner or later—work for His glory and our good.
So perhaps we should all spend a little less time and energy trying to "manipulate" God into giving us what we think is best for us. We all have a tendency to assume we know what our "good" is. Instead, spend more time this week loving God and trusting his call and purpose.
