Malachi 3:14-18

Ye have said, It is vain to serve God; and what profit is it that we have kept his charge, and that we have walked mournfully before Jehovah of hosts? and now we call the proud happy; yea, they that work wickedness are built up; yea, they tempt God, and escape. Then they that feared Jehovah spake one with another; and Jehovah hearkened, and heard, and a book of remembrance was written before him, for them that feared Jehovah, and that thought upon his name. And they shall be mine, saith Jehovah of hosts, even mine own possession, in the day that I make; and I will spare them, as a man spareth his own son that serveth him. Then shall ye return and discern between the righteous and the wicked, between him that serveth God and him that serveth him not.
