Jesus, speaking of Himself, said in John 14:11: "Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the miracles themselves." Jesus did not come with words only. He preached repent for the Kingdom of God is at hand and then demonstrated it. His works were the validation of His words. The book of Mark focuses on Jesus as a man of action. The phrase "at once" or the word "immediately" is used more than thirty times in this book to describe events. It is a book with the stress on action and facts rather than themes or topics. Both Matthew and Luke use far more verses to describe the same events as Mark. For example Luke uses 23 verses to describe John the Baptist's ministry to Mark's 10. If you are an action person, one who wants to do rather than talk, this is the book for you. Jesus puts wings to His words Let the Wonder Worker described in Mark captivate your heart and empower you for great works as He promised.
