This is called conscience…

When God created man He sowed in him something divine, a certain thought which has in itself, like a spark, both light and warmth; a thought which enlightens the mind and indicates to it what is good and what is evil—this is called conscience, and it is a natural law.
–Saint Dorotheus of Gaza (Sixth Century)

God built heaven and earth…

God built heaven and earth to be the dwelling place of the human race. But He also built the human body and soul to make them His own abode, so that He might dwell therein and rest there as in a well kept house. . . In their houses, human beings carefully accumulate their wealth. The Lord in His house, our soul and body, amasses and stores up the heavenly riches of the Spirit.
–Pseudo-Macarius (Fifth Century)
