Intense Happiness Comes From Following God's Will
When a soul recognizes the will of God and shows a readiness to submit to it entirely, then God gives himself to such a soul and renders it most powerful succor under all circumstances. Thus it experiences a great happiness in this advent of God and enjoys it the more, the more it has learned to abandon itself at every moment to his adorable will.
