"Nevertheless my lovingkindness will I not utterly take from him, nor suffer my faithfulness to fail. My covenant will I not break, nor alter the thing that is gone out of my lips." Psalm 89:33, 34
We live in a changeable, ever-changing world. All without us is stamped with mutation, death, and decay; and as regards ourselves everything within us tells us how frail, weak, and mutable we are. Thus, as viewed by the eye of sense and reason, uncertainty and changeability are ever seen to be deeply stamped, not only on every event of time, but on all we are and have in body and soul; and this experience of what we feel in ourselves and see in all around us often wonderfully tries both our faith and hope, for we are apt to measure God by ourselves, and judge of our state before him, not according to his word, but according to the varying thoughts and exercises of our mind.
But when we can look by faith through all these mists and fogs which, as resting on the lower grounds of our soul, so often obscure our view of divine realities, to the fixed purposes of God as manifested in an everlasting covenant, ordered in all things and sure, and have at the same time some testimony of our interest therein, ground is thus afforded both for faith and hope as resting, not on our ever-changing feelings, but on the word and promise of him that cannot lie.
It was thus David was comforted on his bed of languishing when the cold damps of death sat upon his brow (2 Samuel 23:5). It was then in this "everlasting covenant, ordered in all things, and sure," that even before the world was formed, man made, or sin committed, a Saviour was provided, a Redeemer set up, and the persons of the redeemed chosen in him and given to him. How can we think, then, that any changing and changeable events in time can alter and frustrate what was thus absolutely fixed by firm and sovereign decree, or that any mutable circumstances in ourselves or others can defeat and disannul the eternal purposes of God?
