Abandonment to Divine Providence reminds the reader that God is in charge of every moment of our lives.
Nothing happens to us without the permission of a God Who loves us and Who can and will order all things to our good.
De Caussade shows the reader that God has ordered our lives specifically to our good. What is happening is not random but rather the result of a loving plan. We do not have to understand what is happening, but we have only to believe that God is in charge. Trust in the Lord is a measure of our love for Him.
Sanctity consists in doing always the Will of God. We know that we are doing God's Will when we fulfill our daily duties and when we accept with trustful surrender whatever comes our way. De Caussade calls this "the duty of the present moment." Surrender does not mean passively accepting injustice or evil but rather seeking God's Will in dealing with it. Only in surrender to the Will of God will we find peace.
St. Therese of Liseaux was profoundly influenced by de Caussade's spirituality. Her "little way" of self-abandonment, moment by moment, is a practical treatise on how to put de Caussade's advice into action.
The book is short but the influence it can have on one's spiritual life will be life long. You will never view life the same, after completing this book. The message of Abandonment to Divine Providence will stay with one for a lifetime.
