Otherwise; The treasure hidden in the field is the desire of heaven; the field in which the treasure is hidden is the discipline of heavenly learning; this, when a man finds, he hides, in order that he may preserve it; for zeal and affections heavenward it is not enough that we protect from evil spirits, if we do not protect from, human praises. For in this present life we are in the way which leads to our country, and evil spirits as robbers beset us in our journey.
Those therefore who carry their treasure openly, they seek to plunder in the way. When I say this, I do not mean that our neighbours should not see our works, but that in what we do, we should not seek praise from without. The kingdom of heaven is therefore compared to things of earth, that the mind may rise from things familiar to things unknown, and may learn to love the unknown by that which it knows is loved when known.
It follows, “And for joy thereof he goeth and selleth all that he hath, and buyeth that field.” He it is that selleth all he hath and buyeth the field, who, renouncing fleshly delights, tramples upon all his worldly desires in his anxiety for the heavenly discipline. [margin note: Col 2:3]
