In this sonnet the message is to show inner conflict of a man who had promised to do a great task but unfortunately when the time comes he is collided with the desister,making him complete blind at the age of forty five.He is a deeply religious man and it shakes his faith in Providence so much that unrest erupt into his innerself.But it is soon resolved that every man should bow before the Will of God.The sonnet thus is the picture of a crisis faced by a Milton,a sublime person bent upon the service of mankind.He is of the opinion that it is the gift of God and it is duty to make the best use of it.God does not worry of our worships because his state is kingly,thousands at his decree and pass over land and ocean without rest.The resultof it is the balance that the poet finds in the faith in God.
Whatever God does is for the best and thus no great disaster is
really a disaster but a manifestation of God`s mercy.Hence we should not lose the spirit but we should carry on to serve God.By service man is known as well as love to his Lord is known.
