What is meant by the word "power?" It is a term much used in the New Testament. "The kingdom of God," it is declared, "is not in word, but in power;" and true faith is said to "stand not in the wisdom of men, but in the power of God."
What, then, is power? It is a divine operation that God himself puts forth in the soul. It cannot be described by words, nor explained so as to be understood by our mental capacity. It must be felt to be known; and must be realised in a man's own soul before he can have any spiritual conception of it.
But "thy people," we read, "shall be willing in the day of thy power." And when the gospel does come to the soul by the application of the blessed Spirit, and a divine power accompanies it, though the power itself cannot be described even by the person himself, it is made known by the effects which follow it. For instance, here is a poor wretch condemned by the law, and in his apprehensions lying for ever under its fearful curse. He may, perhaps, see there is salvation in Christ, and know in his judgment there is salvation in no other; but he cannot lay hold of Christ, nor get from under the condemnation he feels. Why? Because the gospel is not made the power of God unto salvation to his soul.
But how he begs, cries, prays, and supplicates God to have mercy on him. Continually he is endeavouring to seek God, and beseech him to have mercy on his soul. But he cannot get peace to his conscience; he is still in trouble and distress, bowed down with bondage, guilt, and fear. Here is a man longing for "power." Now, when the Lord is pleased to apply some portion of his blessed word to his soul, or to speak home some particular promise, the power which accompanies this raises up a special faith, whereby that portion of God's holy word, which speaks of Christ, or that particular promise is laid hold of.
Here, then, is "power" communicated with the gospel. The gospel has now come to him, "not in word only," as it might often have done before, leaving him all the while in guilt and fear, but with "power;" and, by the faith thus raised up, he believes in Jesus to the saving of his soul. He could not believe in him before, for his faith, such as it was, being devoid of power, left him where it found him, as forlorn and helpless as the man who fell among thieves. No. He might as well attempt to create a world, as to believe in the Son of God unto deliverance; but no sooner does he believe what the Holy Spirit applies, than a sweet and sacred power comes into his soul, which takes away his doubts and fears; dispels guilt from his conscience; banishes the mists and fogs that for months have hung over his soul; reveals in him a precious Jesus; makes the promises of the gospel to glitter before his eyes like dew-drops in autumn; and gives him an unspeakable nearness to God, through the Person, blood, and righteousness of Christ, such as he never knew until the gospel came with power, and faith was raised up in his soul.
