Interesting questions! It fills my heart with joy to see my future colleagues wrestle with substantial questions such as these. Someone mentioned temptation. That's key! Removing yourself from temptations, especially when it competes with your "life" (as in life of personal relationship with Jesus Christ) is vital in re-calibrating, so to speak. Thank you for reminding us all what is really important in this life, which is glorying God and enjoying Him forever. SDN and medicine are important too, but can only be secondary to our spiritual development as morally responsible and loving children of God. 🙂
