Some of the prominent examples:

"There is a way to be good again" (Hosseini 2).
A line repeated many times, and for good reason. Amir realizes
that there is a way to find the redemption he so desperately wants.
Redemption in the form of helping a particular child.

"A way to end the cycle. With a little boy. An orphan.
Hassan's son. Somewhere in Kabul." (Hosseini 227). The redemption
comes to him in the form of Hassan's child. Through Sohrab, Amir is
able to do wat he couldn't back in the alley and be brave.

"I looked down at Sohrab. One corner of his mouth had curled up
just so. A smile." (Hosseini 370). After bringing Sorhab back from
Afganistan, Amir feels almost redeemed, but not quite. In helping
Sohrab be happy again, Amir completes the task given to him to
Rahim Kahn, to be good again.
