Lord, I don’t want my tears to be born merely of self-pity, but of confession, repentance, gratitude and restoration. Let my life be poured out as a drink offering, if there be pain let it overflow only to your praise – the praise of your sufficiency.
For I am already being poured out as a drink offering, and the time of my departure has come. I have fought the good fight, I have finished the course, I have kept the faith; in the future there is laid up for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day; and not only to me, but also to all who have loved His appearing. 2 Timothy 4:6-8

C.S. Lewis wrote a book on pain, some great thoughts.
That unparalleled author has taught me so much.
