Just as the growth and fruits of plants are different according to the sort of the seeds and the field, the fruits of our lives are different according what kind of heart fields we have and what kind of seeds we sow in our hearts. A diligent person can cultivate even a waste land into a good one. In the same way, our heart changes according to the amount of our efforts. The secret of the change of our heart is the power of the Word of God. The Word of God washes away and renews our heart like clean water, so that anyone who obeys the Word can be made beautiful.
