The Path to Peace is a wonderful book that will lead you to the Heart of God.
Here is a sample of some of the uplifting thoughts to be found in The Path to Peace:

“Keep your wants, your joys, your sorrows, your cares, and your fears before God.  You cannot burden Him; you cannot weary Him.  He who numbers the hairs of your head is not indifferent to the wants of His children. His heart of love is touched by our sorrows and even by our utterances of them.  There is no chapter in our experience too dark for Him to read; there is no perplexity too difficult for Him to unravel. No calamity can befall the least of His children, no anxiety harass the soul, no joy cheer, no sincere prayer escape the lips, of which our heavenly Father is unobservant, or in which He takes no immediate interest.  Take to Him everything that perplexes the mind.  Nothing is too great for Him to bear, for He holds up worlds.  He rules over all the affairs of the universe. Nothing that in any way concerns our peace is too small for Him to notice.”  The Path to Peace page 49
