Charles Spurgeon Commentary 1 Thessalonians 5:15-16

"See that none render unto any one evil for evil; but always follow after that which is good, one toward another, and toward all. Rejoice always;" — 1 Thessalonians 5:15-16 (ASV)

But ever follow that which is good, both among yourselves, and to all men. Rejoice evermore.

You have always something to rejoice in; make the world ring with Christian music.
