May the God of hope fill you with all joy and peace in believing. Paul wishes not a vague mood here but concrete fullness: joy and peace that come from faith, not from circumstances.
Hope in the New Covenant is not uncertainty. It is confident expectation because it is based on God's character. And where hope stands, accusation has no ground.
Today: let yourself be filled with joy and peace. Not as performance but as a gift from the God of hope.
