Alma spends three chapters calling Corianton to repentance following his indiscretions with the harlot Isabel. most of that time, however, is spent teaching Corianton the gospel afresh.
We get a wonderful perspective on the resurrection, the spirit world after death, the workings of the redemption, and the justice vs mercy reality. we hear about Adam and Eve and why it was necessary for them, and us, to go through this mortality.
In the end we see the renewed hope and faith of Corianton.
I hope you enjoy it and find it uplifting and encouraging.
