We know that our standing before God is not determined by our works but, rather, Christ's work on the cross. That point was made clear in the recent sermon from Matthew 7:21-23. But the Bible doesn't allow us to rest in "easy believe-ism," either. Instead, we're told to "Work out [our] own salvation with fear and trembling" (Philippians 2:12). For the Christian, purity isn't an option; it's a mandate. In our article for this week, author, speaker, and long-time pastor, John Piper (www.DesiringGod.org) encourages us to be serious about striving for purity, just as the Scriptures do.
