Note 18 at Eph. 5:10: The word "proving" as used here (see ref. h at this verse) is speaking of making manifest to the physical realm or showing openly to the world our new nature as children of light which was spoken of in verse 8. Paul had spoken of Christians as children of light in their hearts (see note 16 at v. 8). Now he is saying, "Display that new nature through your actions so everyone can see the type of actions that are pleasing to God." This goes along with the old saying, "Your life is the only Bible some people will ever read." Make sure they are being presented the truth.
