Here are 2 resources to better help you understand Good Friday, Easter, and the life of Jesus.

Desiring God put out an amazing article walking through the events of Good Friday.  It is a definite read.

A new book Titled, Behold the Kingdom of Glory by Russ Ramsey is really good.  It is a narrative of the life, death, and resurrection of Jesus.  It is a fun read that has scriptures from all 4 gospels woven together.  I have thoroughly enjoyed reading it this Easter Season.
