Your external circumstances may change, toil may take the place of rest, sickness of health, trials may thicken within and without. Externally, you are the prey of such circumstances; but if your heart is stayed on God, no changes or chances can touch it, and all that may befall you will but draw you closer to Him. Whatever the present moment may bring, your knowledge that it is His will, and that your future heavenly life will be influenced by it, will make all not only tolerable, but welcome to you, while no vicissitudes can affect you greatly, knowing that He who holds you in His powerful hand cannot change, but abideth forever.
