Malachi 3:16-17

16Then those who feared the Lord [with awe-filled reverence] spoke to one another; and the Lord paid attention and heard it, and a book of remembrance was written before Him of those who fear the Lord [with an attitude of reverence and respect] and who esteem His name.

17“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.”
