Jonah 3 is the greatest crusade meeting that ever took place in the history of mankind. The whole city turned to God and repented of their sins. This took place because of one preacher, who grudgingly preached the words of God.
The Ninevites understood their sins and the need for God because someone told them. Subtract Jonah the preacher it would have been judgment.
And this is true for today. Without the Gospel very few realise their sins and the darkness they are living in. Without the light they will not see their darkness. Whether someone be saved has a lot to do with whether they get to hear the word of God.
In sharing Christ we often ask the question, "Would she believes?" That is the wrong question. Asking the right question is highly important. The right question is "Would I tell?" Jonah 3 teaches us that.
Lord, I am so grateful I am saved. Yet I pray I won't stop here. Let's this gratitude compels me to tell of you. In Your Name, Amen
