Romans 8:28 "And we know that all things work together for good for those who love God, for those who are called according to his purpose."
In this verse the Apostle Paul shares a privilege of those who love God and those called to His purpose. He begins by saying, "and we know," which means, in this we're sure and confident. As followers of Christ, its our privilege to be confident, knowing no matter our situation, good or bad, directly or indirectly, when it feels right and when it doesn't, its working for our good.
Everything we face, or that is brought upon us, works for our spiritual benefit. Whether it's breaking us off from sin, bringing us closer to God, pulling us from the world, or fitting us for heaven, it works for us! We must be "thankful" for this privilege and confidence that we have in God. Knowing no matter what the case may be, because we love God and are called according to His, EVERYTHING is going to work together for the good that God desires for our lives.
