He gives strength to those who are tired; to the ones who lack power, he gives renewed energy.
[Isa 40:29 NET]
The Lord often gives his people power to take a longing, languishing look at the blood and righteousness of Jesus; to come to the Lord, as “mighty to save,” with the same feelings with which Esther went into the presence of the king—“I will go in, and if I perish, I perish.” It is with them sometimes as with the four lepers who sat at the entering in of the gate of Samaria—“And they said one to another, Why sit here until we die? If we say, We will enter into the city, then the famine is in the city, and we shall die there—and if we sit still here, we die also. Now therefore come, and let us fall unto the host of the Syrians—if they save us alive, we shall live; and if they kill us, we shall but die” (2 Kings 7:3, 4). And so the Lord’s people are sometimes brought to this state—“If I perish, I will perish at his footstool.” If he gives no answer of mercy, they will still cling to his feet, and beseech him to look upon, and save them.
Now this is “power,” real power. Despair would have laid hold upon their soul, if this secret power had not been given to them. Sometimes we learn this by painful experience. Our trials sometimes stun us, and then there is no power to seek or pray. But when power is given, there is a pleading with the Lord, a going out of the heart’s desires after him, and a fulfillment in the soul of the experience described by the prophet, “I will wait upon the Lord, that hides his face from the house of Jacob, and I will look for him.”
God gives power also to believe; for it is the work of the blessed Spirit to raise up living faith in the heart. He gives power to hope; for it is only so far as he communicates power, that we can cast forth this anchor of the soul. He gives power to love; for it is only as he gives power, that we feel any measure of affection either to the Lord or to his people. In a word, every spiritual desire, every breath of fervent prayer, every movement of the soul heavenward, every trusting in God’s name, relying on his word, and hanging upon his promises, spring out of power communicated by the Lord to the faint and feeble.
