I will strengthen thee.
God has a strong reserve with which to discharge this engagement; for he is able to do all things. Believer, till thou canst drain dry the ocean of omnipotence, till thou canst break into pieces the towering mountains of almighty strength, thou never needest to fear. Think not that the strength of man shall ever be able to overcome the power of God. Whilst the earth’s huge pillars stand, thou hast enough reason to abide firm in thy faith. The same God who directs the earth in its orbit, who feeds the burning furnace of the sun, and trims the lamps of heaven, has promised to supply thee with daily strength. While he is able to uphold the universe, dream not that he will prove unable to fulfil his own promises. Remember what he did in the days of old, in the former generations. Remember how he spoke and it was done; how he commanded, and it stood fast. Shall he that created the world grow weary? He hangeth the world upon nothing; shall he who doth this be unable to support his children? Shall he be unfaithful to his word for want of power? Who is it that restrains the tempest? Doth not he ride upon the wings of the wind, and make the clouds his chariots, and hold the ocean in the hollow of his hand? How can he fail thee? When he has put such a faithful promise as this on record, wilt thou for a moment indulge the thought that he has out promised himself, and gone beyond his power to fulfil? Ah, no! Thou canst doubt no longer.
O thou who art my God and my strength, I can believe that this promise shall be fulfilled, for the boundless reservoir of thy grace can never be exhausted, and the overflowing storehouse of thy strength can never be emptied by thy friends or rifled by thine enemies.
Now let the feeble all be strong,
And make Jehovah’s arm their song.
The spot of his children.
What is the secret spot which infallibly betokens the child of God? It were vain presumption to decide this upon our own judgment; but God’s word reveals it to us, and we may tread surely where we have revelation to be our guide. Now, we are told concerning our Lord, “to as many as received him, to them gave he power to become the sons of God, even to as many as believed on his name.” Then, if I have received Christ Jesus into my heart, I am a child of God. That reception is described in the same verse as believing on the name of Jesus Christ. If, then, I believe on Jesus Christ’s name-that is, simply from my heart trust myself with the crucified, but now exalted, Redeemer, I am a member of the family of the Most High. Whatever else I may not have, if I have this, I have the privilege to become a child of God. Our Lord Jesus puts it in another shape. “My sheep hear my voice, and I know them, and they follow me.” Here is the matter in a nutshell. Christ appears as a shepherd to his own sheep, not to others. As soon as he appears, his own sheep perceive him-they trust him, they are prepared to follow him; he knows them, and they know him-there is a mutual knowledge-there is a constant connection between them. Thus the one mark, the sure mark, the infallible mark of regeneration and adoption is a hearty faith in the appointed Redeemer. Reader, are you in doubt, are you uncertain whether you bear the secret mark of God’s children? Then let not an hour pass over your head till you have said, “Search me, O God, and know my heart.” Trifle not here, I adjure you! If you must trifle anywhere, let it be about some secondary matter: your health, if you will, or the title deeds of your estate; but about your soul, your never-dying soul and its eternal destinies, I beseech you to be in earnest. Make sure work for eternity.
