What are 4 things that the Receiver-in-Training must do?

The Chief Elder lists the necessary qualities as: Intelligence, Integrity, Courage, and Wisdom. Furthermore, she lists the mysterious trait of being able to "see beyond."

Explanation:

The Elders seem quite sure that Jonas either possesses or has the potential for all of these traits, and as he thinks it over, Jonas believes it himself. Though he is uncertain of the implication, he has before felt himself beginning to "see beyond."
