Why do the nations rage and the peoples plot in vain? The nations in plural, the Kings as representing the leaders as in religious as in political. We are yet to see their rage though we know it is there, it is building, they plot, they plot in vain. This is what is and is coming. When you try and save yourself it is a vainity. We are saved by grace through faith and it is not of ourselves it is the gift of God, not by works so that no one can boast. https://biblehub.com/psalms/2-2.htm
