章伯斯(Oswald Chambers,1874-1917)被誉为“近代奥秘派”(Modern Mystical)的使徒，是近代神兴起的一位先知和属灵的导师。
章伯斯所发表出来的属灵的信息和亮光，却照亮了近代的信徒，而其影响力也愈来愈强，以致成为千万信徒每日阅读属灵经典之著作《竭诚为主》(My Utmost of
His Highest)一书，该书也成为所有宣教士属灵生命和事奉的指引。
你是否每日都有灵修？你是否在灵修中与神有亲密而甜美的相交？现在的信徒过分注重主观式、默想式，甚至是随意发挥式的灵修，这使人在灵修中尝不到主恩的滋味，也使灵修难于成为生活中不可或缺的一部分。章伯斯这本经典的灵修作品《竭诚为主》坚持救赎的客观性与真理性，提醒我们信仰的根基和经历神的同在的意义。这些都藏在这本充满古旧信息的灵修作品中，也显示在十字架上带着钉痕的手上，每一天把我们带到神的面前，使我们心灵得医治，生命得动力。
