You said: “I don’t understand why as a civilization we fail to advance not technologically but spiritually.”
Because spirituality of the civilization is accomplished one individual at a time…it is a slow process due to the fact that some or all of our offspring fall by the wayside due to lack of knowledge of God.
Train up a child in the way he should go, And even when he is old he will not depart from it. Proverbs 22:6.
