Paul, an apostle of Jesus Christ by the commandment of God our Saviour, and Lord Jesus Christ, which is our hope; Paul an apostle - by the commandment of God - We have already seen that the term αποστολος, apostle, literally signifies a person sent from one to another, without implying any particular dignity in the person, or importance in the message. But it is differently used in the New Testament, being applied to those who were sent expressly from God Almighty, with the message of salvation to mankind. It is, therefore, the highest character any human being can have; and he message is the most important which even God himself can send to his intelligent creatures. It was by the express command of God that St. Paul went to the Gentiles preaching the doctrine of salvation by faith in Christ Jesus.
Jesus Christ - our hope - Without Jesus, the world was hopeless; the expectation of being saved can only come to mankind by his Gospel. He is called our hope, as he is called our life, our peace, our righteousness, etc., because from him hope, life, peace, righteousness, and all other blessings proceed.
