And Jonah began to enter into the city a day’s journey, and he cried, and said, Yet forty days, and Nineveh shall be overthrown (Jonah 3:4.)
The book of Jonah is not only a testimony to God’s sovereignty, but it is a testimony to the effectiveness of His word. God sent a mean, reluctant preacher, with a halfhearted sermon, to a wicked and vicious people, and turned them from their course of sin.
Here is this preacher, preaching a message that, on his part, can neither be called heartfelt, nor compassionate. God does not need your help in the equation to work His word into the hearts of men. He is God all by Himself. And even so, He is pleased to use men to facilitate His word, to bear His word, and to distribute His word. Yet, only God can deliver the right message, at the right time, to the right heart. You may be warm and inviting in your speech, but that won’t open a closed heart. You may be cold and callous, as Jonah, and that won’t close an open heart.
