Life has become a bitter drink to me, and yet it must be taken in drops, counted one by one. - Søren Kierkegaard

Besides, Christianity is not a doctrine to be taught, but rather a life to be lived.

The person who is going to preach ought to live in the Christian thoughts and ideas: they ought to be his daily life. If so – this is the view of Christianity – then you, too, will have eloquence enough and precisely that which is needed when you speak extemporaneously without specific preparation. However, it is fallacious eloquence if someone, without otherwise occupying himself with, without living in these thoughts, once in a while sits down and laboriously collects such thoughts, perhaps in the field of literature, and then works them into a well-composed discourse, which is then committed to memory and delivered superbly, with respect both to voice and diction and gestures.

Seek first God's Kingdom, that is, become like the lilies and the birds, become perfectly silent — then shall the rest be added unto you.
