This phrase-- "Into thine hand, I commend my spirit" --is seen in both Psalm 31:5 and Luke 23:46. In Psalm, the writer is acknowledging the surrender of their soul to God. In Luke, Jesus is speaking on the cross moments before he dies and is turning over the future of His spirit, soon to depart his body, to His father. Interestingly, the Psalm version, which includes the phrase "thou hast redeemed me, O Lord, God of truth" has a great deal to do with what Christ was doing on the cross. While this part of the Psalm was not spoken in Luke, Christ's actions redeemed a condemned race into eternal life, and the entire Psalm reflects that if we are willing to give up our souls to Him, we can partake in that.
There are so many incredible verses, it's hard to pick just one. So I don't! :-)
They come and go as life comes and goes. The ones that have been on my mind for some time, however, are Psalm 17:8: "Keep me as the apple of your eye; hide me in the shadow of your wings", and Psalm 91:4: "He will cover you with his feathers, and under his wings you will find refuge; his faithfulness will be your shield and rampart".
Life is difficult. Nursing often puts people in the middle of that difficulty. I attempt to consistantly seek my own refuge in the shadow of the wings as I deal with a demanding schedule, seriously ill patients, out-of-touch managers, angry coworkers, unrealistic demands, and the suffering we see daily at the bedsides of the ill and ailing. When I have patients at the end of life when there is nothing left for my earthly hands to do, I have turned my dying patients over to the shadow of the wings. In general, I pray that when patients come under my care, regardless of what they believe, that they would know peace in that gentle shadow.
