“My soul is cast down within me; therefore I remember you from the land of Jordan and of Hermon, from Mount Mizar. Deep calls to deep at the roar of your waterfalls; all your breakers and your waves have gone over me. By day the Lord commands his steadfast love, and at night his song is with me, a prayer to the God of my life.”

A note from Bob; I pray that your relationship with God closely resembles the one described above! If it does, when you feel down (or low), you will remember God’s goodness and let His Deep love, reach you in the deep spot you may be in!
