Calvin points out that God’s word is Godlike:
….as the Prophet possessed the discernment of the Holy Spirit, he penetrated into their hearts and brought out what was hid within. We indeed know this to be the power of the word, as the apostle teaches in the fourth chapter to the Hebrews: for the word partakes of the nature of God himself, from whom it has proceeded; and as God is a searcher of hearts, so also the word penetrates to the marrow, to the inmost thoughts of men, and distinguishes between the feelings and the imaginations.
