Man¡¯s soul is composed of his mind, emotion, and will. To establish the souls of the disciples is to establish them (1) in their (mind), that they may know and understand the Lord and the things concerning Him (1 Cor. 2:16; Phil. 3:10); (2) in their (emotion), that they may love the Lord and have a heart for the Lord¡¯s interest (Mark 12:30; Rom. 16:4); and (3) in their (will), that they may be strong to remain with the Lord and do the things that please the Lord (11:23; Col. 1:10; 1 Thes. 4:1).
