Matthew 13:44-50
The parables of the “treasure hidden in a field,” and the “merchant man seeking goodly pearls,” appear intended to convey one the same lesson. They vary, no doubt, in one striking particular: the “treasure” was found of one who does not seem to have sought it; the “pearl” was found of one who was actually seeking pearls. But the conduct of the finders, in both cases, was precisely alike: both “sold all” to make the thing found their own property; and it is exactly at this point that the instruction of both parables agrees.
These two parables are meant to teach us, that men who are really convinced of the importance of salvation will give up everything to win Christ and eternal life.
