How beautifully expressive are these words of the familiar and condescending manner in which He had hitherto held intercourse with the first pair.

      hid themselves amongst the trees of the garden--Shame, remorse, fear--a sense of guilt--feelings to which they had hitherto been strangers disordered their minds and led them to shun Him whose approach they used to welcome. How foolish to think of eluding His notice (Ps 139:1-12).
