Ephesians 5:6

This verse further stresses the urgency of living lives of love rather than selfishness. The empty words in view would be words teaching that living a moral Christian life is unimportant. They are empty because they are void of content, containing no truth. If the wrath of God is presently coming on the sons of disobedience (cf. Ephesians 2:2), certainly His own sons can expect His discipline when they practice the same things. Since God is holy He deals with sin wherever He finds it, in unbelievers and in believers alike.
