Confidence in God’s sustaining power

The LORD is my shepherd; I shall not want. [2] He maketh me to lie down in green pastures: he leadeth me beside the still waters. [3] He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake. [4] Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me. [5] Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over. [6] Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the LORD for ever. - (Psalms 23:1-6)
