John 3:19-21: “This is the judgment, that the Light has come into the world, and men loved the darkness rather than the Light, for their deeds were evil. For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed. But he who practices the truth comes to the Light, so that his deeds may be manifested as having been wrought in God.”
In every true conversion, a lover of Darkness and a hater of the Light, is given a new heart and nature to want what he once hated. It is a breathtaking miracle of new creation performed by the power of God alone.
