The Word of God is the ONLY spiritual food that gives eternal life. To all the thirsty: Come to the waters; and those who do not have money, come, buy and eat. Come, buy without money and without price, wine and milk. Why do you spend money on what is not bread, and your work on what does not satisfy? Listen to me attentively, and eat of good, and your soul will be delighted with fatness. Incline your ear, and come to me; hear, and your soul shall live; and I will make an everlasting covenant with you, the firm mercies of David. Isaiah 55: 1-3
