Even as a seasoned believer, I found this book to be informative as well as an incredible heart check.
The Gospel
From the beginning, God made the creation, Adam and Eve, and everything was perfect. There was no evil or death in the creation. Because God created mankind with a free will, and he also created the tree of life and the tree of knowledge of good and evil. There was a choice man could make, to walk with God and live, or to walk his own way, but without God.
