2 Corinthians 6:11-7:16.  The temple under the old covenant was a building in Jerusalem, and it could be defiled by people who came in contact with certain things: a dead body, certain animals, etc.  Since the death of Christ on the cross, God has instituted a new covenant, in which the temple is now the lives of believers. That temple can be defiled as well.  Here, Paul points out two things that were defiling the temple at Corinth. 1) partnerships with unbelievers (6:14-7:1). 2) worldly grief [which the ESV Study Bible defines as “remorse brought about by losing the world’s approval”]. 

LORD, we resolve to cleanse ourselves of those things that defile, and serve you wholeheartedly.
