The story is told of Augustine of Hippo, a great philosopher and theologian who wanted so much to understand the doctrine of the Trinity and to be able to explain it logically.
One day as he was walking along the sea shore and reflecting on this – “Father, Son, Holy Spirit; three in one!” – he suddenly saw a little child all alone on the shore. The child made a whole in the sand, ran to the sea with a little cup, filled her cup, came and poured it into the hole she had made in the sand. Back and forth she went to the sea, filled her cup and came and poured it into the hole. Augustine went up to her and said, “Little child, what are doing?” and she replied, “I am trying to empty the sea into this hole.” “How do you think,” Augustine asked her, “that you can empty this immense sea into this tiny hole and with this tiny cup?” To which she replied, ” And you, how do you suppose that with this your small head you can comprehend the immensity of God?” With that the child disappeared.

All sorts of people are fond of repeating the Christian statement that “God is love.” But they seem not to notice that the words ‘God is love’ have no real meaning unless God contains at least two persons. Love is something that one person has for another person. If God was a single person, then before the world was made, He was not love. | C.S. Lewis, Beyond Personality, (Macmillan, 1948) page 21.
