Your quote got me thinking about a passage in the bible;
The Rejection of Jesus at Nazareth
54 He came to his hometown and began to teach the people[
a] in their synagogue, so that they were astounded and said, "Where did this man get this wisdom and these deeds of power?
55 Is not this the carpenter's son? Is not his mother called Mary? And are not his brothers James and Joseph and Simon and Judas?
56 And are not all his sisters with us? Where then did this man get all this?"
57 And they took offense at him. But Jesus said to them, "Prophets are not without honor except in their own country and in their own house."
58 And he did not do many deeds of power there, because of their unbelief.
In that last verse, it would seem that indeed man has some participation in the message of salvation, if only he has ears to hear. How do you understand it?
