St. John of the Cross spoke of dark night of the soul. We all have or had our own dark nights. Mother Teresa had hers that lasted for decades! Whether it's the feeling that God is totally absent, sickness, or any other form of suffering, I see all of them as proof of God's existence or his love. It's because God exists so that we notice his absence. It's because God loves us that he sends us trials and suffering to purify us, readying us for joining him in heaven. We must welcome whatever the Lord sends our way.
