One quote that stood out to me during this read was:
Christ humbled Himself, therefore God exalted Him, Christ will humble us, and keep us humble; let us heartily consent, let us trustfully and joyfully accept all that humbles; the power of Christ will rest upon us. We shall find that the deepest humility is the secret of the truest happiness, of a joy that nothing can destroy.(Murray, Andrew. Humility: The Beauty of Holiness)
Murray points out that we are able to experience true happiness through understanding God's grace placed in our lives!
