Note 6 at Eph. 5:3: The NIV translates this verse as follows: "But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God's holy people." Paul is simply emphasizing that these sexual impurities and covetousness should not ever be a part of the Christian life. Sad to say, many Christians today have abandoned the belief that Christians can live differently than the world. That may be the way we see things in the body of Christ today, but that is not the way it has to be or the way God wants it to be.

Note 7 at Eph. 5:3: The reason for the holiness Paul had just advocated in the first part of this verse, is that we are saints. The very word "saint" denotes separation (see ref. k at this verse). It is the nature of saints to be separate from the sin the world lives in.
