This Scripture passage in 2 Corinthians 6:14 urges us to be pure and undiluted by the world. It tells us to come away from sinful things and be separated unto God. We are not to have anything to do with sinful things because righteousness and unrighteousness do not belong together. Our lives become weak and ineffective when we allow worldliness to come into them. There is so much pressure to act, talk and think like the world. If we are not careful, we will forget that we belong to Jesus and should live to please Him. When Christians allow the world to dilute our testimony, it pollutes our effectiveness. Let us not allow worldly things and matters dilute our testimony. Let us remember never to pollute our lives with impure things and always ask God to keep us true to Him.
