There are manifold ways to think about kinds of people in the world, but one way right out of Scripture is to think about "Sinners in Need of Grace" and "Sinners Saved by Grace."  Either a person has asked Jesus Christ to forgive their sins and by grace through faith (Eph 2:8-9) become a Christian, i.e., a sinner saved by grace, or they have not and are still a sinner in need of this saving grace. We often, then, perhaps understandably, focus on the saved by grace part, as we should, celebrating and praising God. But there's the other part, too, that we are still sinners. What are the implications of this? For more Christian commentary, check my website at rexmrogers.com.
