One thing I forgot to mention which may be the most important point and the reason for the success of The Shack . . .
The main character, Mack, has a deep longing, a hole in his heart, spirit, mind and body. His deep longing is to have a connection with God. That really is the point of the book in my opinion, a man's deep longing, desire to connect with God to ease the pain of the past and the present.
For each one of us, we have a longing, a craving, a desperate desire to connect in a deeper and more fulfilling way with God . . . the question is how we go about filling that hunger.
Come on Sunday and we will talk more about this, since the sermon is on the 4th Beatitude, "Blessed are those who hunger and thirst for righteousness, for they will be filled."
