Evils not ... Among Saints
A Sermon on Ephesians 5:3-5
But sexual immorality and all impurity or covetousness must not even be named among you, as is proper among saints. Let there be no filthiness nor foolish talk nor crude joking, which are out of place, but instead let there be thanksgiving. For you may be sure of this, that everyone who is sexually immoral or impure, or who is covetous (that is, an idolater), has no inheritance in the kingdom of Christ and God. (ESV)
The Christian must never be content with just grasping principles; things the Christian must avoid at all costs; how we are to avoid these things; 'make no provision for the flesh'; the importance of Christian speech; the danger of covetousness includes more than money; a conduct that becomes the saints.
