Thomas Boston, Works, 3:468:
Treasure in heaven is suitable to the nature of the soul. The soul is a spirit, and this treasure is spiritual, containing “all spiritual blessings in heavenly places in Christ.” The soul cannot feed on the things of the world, more than the body can do on ashes. He was a fool that thought his soul could take ease in the treasure laid up in his barns, Luke 12:19. Debase not the high born soul, to match with things of the world. It is an unsuitable match in which there will be no comfort.
