Charles Spurgeon Commentary Malachi 3:18

"Then shall ye return and discern between the righteous and the wicked, between him that serveth God and him that serveth him not." — Malachi 3:18 (ASV)

Then shall you return, and discern between the righteous and the wicked,

Not now, but then; eventually, there will be a distinguishing mark set upon all mankind: Then shall you return, and discern between the righteous and the wicked.
