As Christians who have been born again, we cannot live in our old nature, for that way is dead. Christians now have a new nature, which is in Christ. We must learn to live in this new nature so that it’s possible for us to give godly grace, forgiveness, love and mercy to others. The butterfly can serve as an illustration for us, as a butterfly has a new nature and can never go back to living in its old nature, as a caterpillar. Everything’s new, including its food source, way of eating, its mobility and its appearance among many other things.
