Blessed are the Peacemakers
The 7th Beatitude is Blessed are the Peacemakers
If we remember that God is God and we are not, then we can be at peace because God is competent to take care of everything in my life and the world even when I am not.
And the best way to remember God is in control and not me is to be still and know that He is God.
If we do this, we will be reminded daily that God carries the weight of the world on his shoulders and we do not have to.
But if we do not become still, every day, very quickly we will forget God and take the weight of the world upon our own shoulders. Eventually it will crush us.
Be still. Call to mind that God is in control and then you will know that all will be well.
