Ephesians 5:10

Proving what is well-pleasing to the Lord. A general rule applicable to the whole walk. To prove is to ascertain by test and experiment. Our whole walk should be directed to finding out what things are pleasing to Christ, rejecting at once everything that is not so, and clinging to all that is. We are not to follow the tradition of our people, and not to take a vague view of duty; we are to prove the matter, to put it to the test. For the supreme practical rule of the Christian's life must be to please Christ.
