The righteous v.s. the unrighteous that’s all it comes down to. It’s not rocket science to God. He knows who has been a blessing to him by following his order. As I had said before God will curse those who have not honored him. There is still good in you Judah, you still have a future you just don’t know the big picture. To go in more depth of the text what God is saying is that not everyone will be saved by Jesus, but all will have an opportunity to be saved. God will separate the wicked from the righteous. God is still evaluating till he sends his Son Jesus for the second coming. Be on the look out, continue to be righteous and to honor God in all that you do. It might still be a long time for Jesus to come of his second coming, but you must know all followers of God. GOD WILL NEVER ABANDON YOU. Be righteous in the eyes of God! Be set apart by showing your righteousness.
16 Then those who feared the Lord talked with each other, and the Lord listened and heard. A scroll of remembrance was written in his presence concerning those who feared the Lord and honored his name. 17 “On the day when I act,” says the Lord Almighty, “they will be my treasured possession. I will spare them, just as a father has compassion and spares his son who serves him. 18 And you will again see the distinction between the righteous and the wicked, between those who serve God and those who do not.
