By heaven in this place I understand not the material heavens, for every thing that has a body is earthly. But it behoves that the whole world be despised by him who lays up his treasure in that Heaven, of which it is said, “The heaven of heavens is the Lord’s,” [Ps 115:16] that is, in the spiritual firmament. “For heaven and earth shall pass away;” [Matt 24:35] but we ought not to place our treasure in that which passes away, but in that which abides for ever.
