We want to be strong and unshakable in the joy of our faith. But we don't want to be oblivious to the grievousness of our own sin or the pain of other people's distress. O God, fulfill in us the purpose of your Son in promising that his joy would be in us and that our joy would be full.
Make the fruit of the Spirit - joy - flourish in our lives. Satisfy us in the morning with your steadfast love that we may rejoice and be glad in you. Waken our slumbering souls from the sleep of listlessness. Take away the lukewarmness of our hearts. Fan the flame of zeal for the glory of your name.
May Christ so dwell in our hearts with his indestructible joy that day by day we are conformed more and more to his glad image. And so may we be a place of refuge and eternal refreshment for a hopeless, joy-seeking world of people who do not know they are starved for the glory of the gladness of God in Jesus Christ. In his name we pray, amen."
