As the book will show you, just like in all of Christianity, it is NOT the outward things we try to do, or avoid, that make up who and what we are, but OUR THINKING AND BELIEF.
Many people on here like to ridicule Joseph Prince, but that is almost the entire premise of most of his teaching... "Right Believing Leads to Right Living." If you don't change your mind, your thinking and believing, (the actual meaning of the word, "Repentance") then you are doing nothing more than what Jesus came down on the Pharisees for.... just "whitewashing" the outside of a tomb filled with a dead man's bones.
