John 3:18 Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son.
While St Augustine was working on his book "On the Trinity", he was walking by the seaside one day, meditating on the difficult problem of how God could be three Persons at once. He came upon a little child. The child had dug a little hole in the sand, and with a small spoon or seashell was scooping water from the sea into the small hole. Augustine watched him for a while and finally asked the child what he was doing. The child answered that he would scoop all the water from the sea and pour it into the little hole in the sand. ‘What?’ Augustine said. ‘That is impossible. Obviously, the sea is too large and the hole too small.’ ‘Indeed,’ said the child, ‘but I will sooner draw all the water from the sea and empty it into this hole than you will succeed in penetrating the mystery of the Holy Trinity with your limited understanding.’ Augustine turned away in amazement and when he looked back the child had disappeared.
