Words to encourage, from J.I. Packer, on our assurance:
Do I, as a Christian, understand myself? Do I know my real identity? My own real destiny? I am a child of God. God is my Father; heaven is my home; every day is one day nearer. My Savior is my brother; every Christian is my brother, too. Say it over and over to yourself first thing in the morning, last thing at night, as you wait for the bus, any time when your mind is free, and ask that you may be enabled to live as one who knows it is utterly and completely true.
