Jesus Christ gave authority to the disciples, to heal and cast out demons and commanded them to preach the news of salvation. He told them not to carry luggage, or to arrange themselves very much, simply that they were. This is our life, we have all the authority that God has given us, we should only apply it, without being aware of luggage. Wherever we are we must preach, we must heal, we must cast out devils, on the street, at home, in hospitals, wherever we may be!
