At the close of the book, he asked a few reflective questions on living now in light of Heaven, and they were so helpful that I thought I would share them here. They are convicting, encouraging, and motivating.
Do I daily reflect on my own mortality?
Do I daily realize there are only two destinations - Heaven or Hell - and that I and every person I know will go to one or the other?
Do I daily remind myself that this world is not my home and that everything in it will burn, leaving behind only what's eternal?
Do I daily recognize that my choices and actions have direct influence on the world to come?
Do I daily realize that my life is being examined by God, the Audience of One, and that the only appraisal of my life that will ultimately matter is his?
Do I daily reflect on the fact that my ultimate home will be the New Earth, where I will see God and serve him as a resurrected being in a resurrected human society, where I will overflow with joy and delight in drawing nearer to God by studying him and his creation, and where I will exercise, to God's glory, dominion over his creation?
