Accept that most people view change as a loss and a negative. Rapid change requires engendering a high sense of necessity and urgency in the congregation for success. The Ninevites believed God. They declared a fast, and all of them, from the greatest to the least, put on sackcloth When God saw what they did and how they turned from their evil ways, he had compassion and did not bring upon them the destruction he had threatened. Even the mention of rapid change will be met with the highest level of opposition.
Rapid change is typically superficial.
The one who received the seed that fell on rocky places is the man who hears the word and at once receives it with joy. But since he has no root, he lasts only a short time. When trouble or persecution comes because of the word, he quickly falls away. The incremental process must follow rapid change or it will not last. Incremental change is always necessary.
