Albert Barnes Commentary 1 Corinthians 16:14

"Let all that ye do be done in love." — 1 Corinthians 16:14 (ASV)

Let all your things, etc. All that you do. This direction is repeated because of its great importance, and because it is a summing up of all that he has said in this epistle. See 1 Corinthians 13; 1 Corinthians 14:1. Here he says that charity, or love, was to regulate all that they did. This was a simple rule; and if this was observed, everything would be done well.
