More lives are influenced by emulation than exhortation.
Satan will try to use our troubles to worry and weaken us. But God uses them to strengthen us.
You cannot control sin. Sin will control you. Do not try to manage sin.
To influence others must keep growing themselves.
Until you start thinking right, you will never start behaving right. Repentance always deals with the changing of the mind.
The Christian life is anything but boring.
