Malachi 3:17-18

“They will be Mine,” says the LORD of hosts, “on that day when I publicly recognize them and openly declare them to be My own possession [that is, My very special treasure]. And I will have compassion on them and spare them as a man spares his own son who serves him.” Then you will again distinguish between the righteous and the wicked, between the one who serves God and the one who does not serve Him.
