According to 1 Corinthians 5:12-13 the church would not have any problems if each of us sought to purify our heart before the Lord. The church will see the wicked world change only as much as we live separate lives to the Lord. Hey, perhaps you’re reading this and you are a person practicing sin, why not die to that part of the old life and start living in sincerity and truth?
The church is not called to judge outsiders; we need to witness to them. This is what we Christians need to realize. We are witnesses of Jesus Christ right now in our lives; the only question is what kind are we? Is our life showing people freedom from sin, or is it showing them slavery to sin? Right now, Christian, the people of the world are watching us to see if our walk matches our talk.
