Notice that in both examples the treasure is lost and the shepherd/woman put aside all else to find it. In order to bring the treasure back though the treasure must repent. There is a rejoicing for each finding/repentance. The intellectual process of somehow figuring God out and finding our way back to Him is not at all discussed.
