G0052–ἄγνοια–agnoia

And now, my brothers, I am conscious that you did this, as did your rulers, without knowledge.

ἄγνοιαν agnoian “ignorance”

Those times when men had no knowledge were overlooked by God; but now he gives orders to all men in every place to undergo a change of heart:

ἀγνοίας agnoias “of ignorance”

Whose thoughts are dark, to whom the life of God is strange because they are without knowledge, and their hearts have been made hard;

ἄγνοιαν agnoian “ignorance”

Like children ruled by God, do not go back to the old desires of the time when you were without knowledge:

ἀγνοίᾳ agnoia “ignorance”
