John 3:16 says, "For God so loved the world that He gave His only begotten son that whosoever believeth on Him should not perish but have everlasting life." It is one of the most memorized and frequently quoted verses of Scripture. In this one little verse, Jesus tells us the greatest thing about God, the greatest thing that God ever did and the greatest thing that ever happened to YOU. This GREATEST thing is the subject of this book.
