“In order to save us, God had to live in a man for thirty-three and a half years. Have you ever thought about this? In creating the universe God used only six days, and on the seventh day He rested. Why, then, did God need to live on earth in a man for so many years in order to save us?” In this booklet compiled from Life-study of Luke, Witness Lee gives the marvelous answer to this important question.
