Romans 15:13 : Now the God of hope fill you with all joy and peace in believing, that ye may abound in hope, in the power of the Holy Spirit. Concerning the Messiah Isaiah had said, "On him shall the Gentiles hope." And so to the Gentiles as well as to the Jews God was the God of hope--he made hope possible even to those who formerly had been without God and without hope (Ephesians 2:12). Without this hope there could be no joy and no peace--no peace of mind and no peace with one another. But we are to be filled with joy and peace in believing, in continuous, active believing. And to be filled with joy and peace increases our hope. The power of the Holy Spirit made this hope and peace possible for the Holy Spirit revealed all we know about God and Christ and the plan of salvation, and confirmed that revelation by signs and wonders. And the things the Holy Spirit revealed to us is the source of all our knowledge, joy, peace, and hope.
