Self-righteousness is the largest idol of the human heart – the idol which man loves most and God hates most. Dearly beloved, you will always be going back to this idol. You are always trying to be something in yourself, to gain God’s favour by thinking little of your sin, or by looking to your repentance, tears, prayers ; or by looking to your religious exercises, your frames, etc; or by looking to your graces, the Spirit’s work in your heart. Beware of false Christs. Study sanctification to the utmost, but make not a Christ of it.
Robert Murray McCheyne
