A voice from heaven uttered a WARNING: Blessed the dead who are now dying in the Lord from now on so that they may in the future be caused to rest from their labors, for their deeds now follow with them.
This addresses the willingness of the people of God to now be dying in the Lord
to all that rebels against Him, such that they might live in Him. This is the perseverance of the saints, to be willing to die to our sin so we do not die in our sin.
The goal is “rest” and to cease from our spiritual labors. That is done when we stop trying to be Yahweh over our own lives and we become willing to let God puts to death all the idolatry in our soul that wants to be like God, and we trust that He will do His works in His time through our lives. We need to take His yoke of control, let Him be the Adonai of our lives, and bear the weight of “believing” that He is good, safe, and will keep us secure.
