Steven Furtick says it so well

Grace is power.Power to save. Power to live right. Power to talk right. Power to walk right. Power to give. Power to forgive. Power to do anything God calls you to do in His name. Power to pray. Power to overcome.
Paul could have lived in perpetual guilt for what he had done. Or he could have taken advantage of what God had done for him. But he didn’t. And look at what he became.
You have the same options.
Embrace the power of God’s grace and imagine what you’ll become.
