Gregory of Elvira

To what does this bed refer, upon which the church seeks the one whom its soul loves, if not to the bed of its heart in which wisdom rests, where it seeks our Lord and Savior through continuous meditation? If the bed is the secrecy of the heart, then what is the night in which the church sought the Lord but was unable to find him? Surely it means that the God of light was not easily found in darkness.
