These led the king to feelings of grandeur and a deranged reason. Surrender paved the way to peace. Peace is produced by grace, and involves our obedient response to the gracious will of God the Father, rather than reliance on our own works. Few experience either the personal greatness or the humiliation of Nebuchadnezzar. All who matriculate in God's school of peace must first comprehend His grace.
Grace always comes before peace.
God's order never changes.
