This constant checking before meals and 2 hours after and even during the night, is to prevent glucose rising to levels (9+ mol) that could damage the transplant. I really don't want to do anything that would undo the wonderful work that was done in me by Professor White and his team. Yet checking is an annoying practice causing my poor fingers to protest at all this blood-letting! I can tell by this though that all is well with my amazing surgical outcome.
I don't believe that God wants his children to be constantly looking inward or navel-gazing but I do recognise the need for occasional checking in my spiritual life too. This is just to see that we are not doing any harm to the wonderful work that God has done in us when he saved us. I recall that few lines from the hymnbook of ancient Israel, the book of Psalms, that says "Search me, O God, and know my heart; test me and know my anxious thoughts. Point out anything in me that offends you, and lead me along the path of everlasting life" (Ps 139:23-24). Jesus also initiated what we know as the communion service or Eucharist, and in it we are told to examine our hearts and see if all is well with God's work within us.
I am glad that the Professor's work in me has been so successful this far, but I am more glad that God has also begun a work in me that offers me new life and a new start each day. After saying farewell to a dear friend at her funeral service last week, I am also glad that this work in us leads on into everlasting life. Surgery for the soul if you like!
