Malachi 3:16-18

16Then those who feared the Lord spoke to one another, and the Lord paid attention and listened. A book was written in his presence to be a reminder to those who feared the Lord and respected his name.

17“They will be mine,” says the Lord of Armies. “On that day I will make them my special possession. I will spare them as a man spares his own son who serves him.

18Then you will again see the difference between righteous people and wicked people, between the one who serves God and the one who doesn’t serve him.
