Our Father, who art in heaven. What does this mean? God would by these words tenderly invite us to believe that He is our true Father, and that we are His true children, so that we may with all boldness and confidence ask Him as dear children ask their dear father.
The word “Father” encourages us to pray with confidence, and without fear and doubt.
Rom. 8:15: For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
