To derive the fullest comfort and encouragement from Romans 8:28 we must realize that God is at work in a proactive, not reactive, fashion. That is, God does not just respond to an adversity in our lives to make the best of a bad situation. He knows before He initiates or permits the adversity exactly how He will use it for our good.

We can call sin exactly what it is, regardless of how ugly and shameful it may be, because we know that Jesus bore that sin in His body on the cross.
