Through genetic engineering of its genes there is a plant that bears potatoes on its roots and tomatoes on its branches. But outside of such experimentation, a tree normally bears only one kind of fruit. Likewise, those who believe in God should bear the fruits belonging to God such as fruit of goodness or fruit of the light. It is because many people can receive peace, joy, liberty and life through the true image of Jesus Christ that is gained from people of faith.
"…for the fruit of the Light consists in all goodness and righteousness and truth" (Ephesians 5:9).
