that no one should take advantage of and wrong a brother or sister in this matter; because the Lord is an avenger in all these things, as also we forewarned you and testified.
because that the Lord is the avenger of all such: The thought of judgment is never far from the mind of the apostle. There may be many reasons for living in sanctification and honor, not the least of which is the fact that "we must all appear before the judgment seat of Christ" (2 Corinthians 5:10). In contrast with the gods of the heathen who engaged in vice, the God of heaven is the avenger of vice. However, it should also be noted that not all punishment is reserved for the after-a-while. Punishment for our misdeeds may begin in the here-and-now (Romans 1:24; Romans 1:26; Romans 1:28).
