Lay all your plans before God, to be carried out or given up, as His providence shall indicate. Accept His plans instead of your own, even though their acceptance requires the abandonment of cherished projects. Testimonies, vol. 7, p. 44.
The soul that is yielded to Christ becomes His own fortress, which He holds in a revolted world, and He intends that no authority shall be known in it but His own. A soul thus kept in possession by the heavenly agencies is impregnable to the assaults of Satan. But unless we do yield ourselves to the control of Christ, we shall be dominated by the wicked one. Desire of Ages, p. 324
