The Principle of Human Existence? It’s a GIFT.
“Gift is the principle on which the Creator has based human existence; it is the most pervasive, even if little noticed, reality of our lives. We have life itself by others’ gift of procreation, pregnancy, and childbirth. We are sustained in life by the good things of nature and by the labor, generosity, and society of other human beings. We are educated by the self-giving of our teachers. We are sustained constantly by gifts–love, forgiveness, reconciliation, pleasure. Our entire life is a fabric woven of gifts received, and we ourselves contribute our gifts to the lives of other. GOD is the first source, the prime mover and most lavish giver of all these gifts.” Living on the Border of the Holy, William Countryman, p. 64.
