"A needle will move towards a magnet when once a magnet has moved near it. Our hearts manifest a sweet willingness towards salvation and holiness when the great and glorious goodwill of the Lord operates upon it. It is ours to run to Jesus as if all the running were ours; but the secret truth is that the Lord runs toward us, and this is the very heart of the business." (from Spurgeon's Sermon Notes)
