What a comfort, amid all earth's vicissitudes and changes, this motto-verse! _Earth may_ change. Since the Lord ascended, earth _has_ changed! There are "Written rocks"--manifold more than those of Sinai--that bear engraven on their furrowed brows, "The world passeth away." Ocean's old shores have transgressed their boundaries--kingdoms have risen and fallen--thronging cities have sprung up amid desert wastes--and proud capitals have been levelled with the dust. _Friends_ may change; our very lot and circumstances, in spite of ourselves, may change. Our fondly planned schemes and cherished hopes may vanish into thin air, and the _place_ that now knows us know us no more! But there is ONE that changeth not--a Rock which stands immutable amid all the ceaseless heavings and commotions of this mortal life--and that Rock is Christ! Has he ever failed us? Ask the _tried_ Christian. Ask the _aged_ Christian. That gray-haired believer may be like a solitary oak in the forest--all his compeers cut down--tempest after tempest has sighed and swept amid the branches--tree by tree has succumbed to the blast--there may be nothing but wreck and ruin and devastation all around. Friend after friend has departed; some have _altered_ towards him; kindness may have given way to alien looks and estranged affection; others are removed by _distance_--old familiar faces and scenes have given place to new ones;--others have been called away to the silent grave--sleeping quiet and still in "the narrow house appointed for all living." That aged lonely Christian can clasp his withered hands, and exclaim, through his tears, "_But_ THOU art the same, and _Thy_ years shall have no end." "Heart and flesh do faint and fail, but God is the strength of my heart, and my portion for ever." "My God, I thank thee, Thou dost care for me; I am content rejoicing to go on, Even when my home seems very far away; And over grief, and aching emptiness, And fading hopes a higher joy ariseth. In nightliest hours one lonely spot is bright, High over head, through folds and folds of space; It is the earnest star of all my heavens, And tremulous in the deep-well of my being, Its image answers. * * * * I WILL THINK OF JESUS."[48] But, in addition to the name and nature of Jesus--the Angels added a promise of comfort regarding Him. "He shall _so come_ in like manner as ye have seen Him go into heaven."[49] _Jesus shall come again!_
