If we make God our trust, we have it in our power to control the mind in these things. Through continued exercise it will become strong to battle with internal foes and to subdue self, until there is a complete transformation, and the passions, appetites, and will are brought into perfect subjection. Then there will be daily piety at home and abroad, and when we engage in labor for souls, a power will attend our efforts. The humble Christian will have seasons of devotion which are not spasmodic, fitful, or superstitious, but calm and tranquil, deep, constant, and earnest. The love of God, the practice of holiness, will be pleasant when there is a perfect surrender to God. (2T 507.1) MC VC

The reason why ministers of Christ are no more successful in their labors is that they are not unselfishly devoted to the work. The interest of some is divided; they are double-minded. The cares of this life engage their attention, and they do not realize how sacred is the work of the minister. Such may complain of darkness, of great unbelief, of infidelity. The reason for this is, they are not right with God; they do not see the importance of making a full and entire consecration to Him. They serve God a little, but themselves more. They pray but little. (2T 507.2) MC VC
