Looking at joy in trials brought to mind this quote from Jurgen Moltmann which describes a much better alternative to what is sometimes called heavenly-mindedness (a misleading phrase).
That is why faith, wherever it develops into hope, causes not rest but unrest, not patience but impatience. It does not calm the unquiet heart, but is itself this unquiet heart in man. Those who hope in Christ can no longer put up with reality as it is, but begin to suffer under it, to contradict it. Peace with God means conflict with the world, for the goad of the promised future stabs inexorably into the flesh of every unfulfilled present. Jurgen Moltmann
