Two things fill the mind

Two things fill the mind with ever new and increasing admiration and awe, the more often and steadily reflection is occupied with them: the starry heaven above me and the moral law within me. Neither of them need I seek and merely suspect as if shrouded in obscurity or rapture beyond my own horizon; I see them before me and connect them immediately with my existence. -Immanuel Kant (born April 22, 1724)

so that I may participate in it fully

I do not serve God only in the brief moments during which I am taking part in a religious service, or reading the Bible, or saying my prayers, or talking about him in some book I am writing, or discussing the meaning of life with a patient or a friend. 

I serve him quite as much when I am giving a patient an injection, or lancing an abscess, or writing a prescription, or giving a piece of good advice. Or again, I serve him quite as much when I am reading the newspaper, traveling, laughing at a joke, or soldering a joint in an electric wire. I serve him by taking an interest in everything, because he is interested in everything, because he has created everything and has put me in his creation so that I may participate in it fully. 

“It is a great mistake,” wrote Archbishop William Temple, “to suppose that God is interested only, or even primarily in religion.”
