"I am the Almighty God: walk before Me, and be thou perfect." -- Genesis 17:1.
Thirteen long years passed slowly on after the return of Hagar to Abraham's camp. The child Ishmael was born, and grew up in the patriarch's house -- the acknowledged heir of the camp, and yet showing symptoms of the wild-ass nature of which the angel had spoken (16:12 RV). Not a little perplexed must Abraham have been with those strange manifestations; and yet the heart of the old man warmed to the lad, and clung to him, often asking that Ishmael might live before God.
And throughout that long period there was no fresh appearance, no new announcement. Never since God had spoken to him in Charran had there been so long a pause. And it must have been a terrible ordeal, driving him back on the promise which had been given, and searching his heart to ascertain if the cause lay within himself. Such silences have always exercised the hearts of God's saints, leading them to say with the Psalmist: "Be not silent to me; lest, if Thou be silent to me, I become like them that go down into the pit" (Psalm 28:1). And yet they are to the heart what the long silence of winter is to the world of nature, in preparing it for the outburst of spring.
Some people are ever on the outlook for Divine appearances, for special manifestations, for celestial voices. If these are withheld, they are almost ready to break their hearts. And their life tends to an incessant straining after some startling evidence of the nearness and the love of God. This feverishness is unwholesome and mistaken. Such manifestations are, indeed, delightful; but they are meant as the bright surprises, and not as the rule of Christian life: they are flung into our lives as a holiday into the school routine of a child, awakening thrilling and unexpected emotions of Joy. It is true that they are liable to be withheld when we are walking at a distance from God, or indulging in coldheartedness and sin. But it is not always so. And when the child of God has lost these bright visitations for long and sad intervals -- if, so far as can be ascertained, there is no sense of condemnation on the heart for known unfaithfulness -- then it must be believed that they are withheld, not in consequence of palpable sin, but to test the inner life, and to teach the necessity of basing it on faith, rather than on feelings however gladsome, or experiences however divine.
At last, "when Abram was ninety years old and nine," the Lord appeared unto him again, and gave him a new revelation of Himself; unfolded the terms of His covenant; and addressed to him that memorable charge, which rings its summons in the ear and heart of every believer still: "Walk before Me, and be thou perfect."
