a prayer about The Joy of Jesus Christ

mark 2 section on fasting basically says... when Jesus shows up there is joy... b/c Jesus is full of joy....
Father, it is a great comfort to us that you and your Son
are never glib and never gloomy. We delight in the truth
that you can be infinitely happy without being callous
to our pain. We stand in wonder that the light of Jesus’
joy makes a rainbow in the tears on his face. We long
to be like this. 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....... (john piper)
