This is a brilliant message, the unrighteous and the ungodly have no place in God's kingdoms, ungodliness are the things, the sins that are keeping us away from fellowships with God, the bible says sin is like a filthy rag, and it also says blessed is the man who walketh not in the ways of the ungodliness.
We must not be unequally yoked with unbelievers lest we ourselves become like them, but we must strive hard to do our best in getting them to the kingdom of God.
