Mountains and Valleys in the Ministry of Jesus [EPUB ebook] 

It is impossible to
study the records of the life of Jesus without noticing how often He retired to
the mountains. Amid the loneliness of their silent strength, He seemed to
breathe the atmosphere of the ages, and to enter into communion with His Father
in special degree. It is equally impossible in such study to fail to notice His
loyalty to the valleys, and the places where men gathered in crowds. It would
be quite true to say that. He loved the mountains, but lived during most of His
public life in the valleys.
