1 Kings 19:12 - Joseph Benson’s Commentary on the Old and New Testaments

After the fire a still small voice To intimate, that God would do his work in and for Israel in his own time, not by might or power, but by his own Spirit, (Zechariah 4:6,) which moves with a powerful, but yet with a sweet and gentle gate. “Elijah had perhaps expected to carry all before him, with a high hand, and with continued miracles and judgments: or he had supposed that the desired reformation was to be effected by the sanction of civil authority, or the support of the people at large; whereas, having gained their attention by the famine and its gracious removal, in answer to his prayers, by calling for and obtaining fire from heaven to consume the sacrifice, and by the execution of Baal's priests, he ought to have proceeded to instruct them with meekness and gentleness, publicly and from house to house, and to have excited others to assist him; and then the Lord would have blessed that small still voice for the most important purposes, notwithstanding the persecuting rage of Ahab and Jezebel, and the general apostacy of the people. Thus miracles in the first ages of Christianity called men's attention to the preaching of the gospel; which, as a small still voice, was the power of God to salvation to thousands and millions.” Scott. For faith comes by hearing the word of God, and miracles do but make way for it.
