I came across this one while preparing for last week's opening sermon on the book of Exodus.
"Avoid a sugared gospel as you would shun sugar of lead. Seek the gospel which rips up and tears and cuts and wounds and hacks and even kills, for that is the gospel that makes alive again. And when you have found it, give good heed to it. Let it enter into your inmost being. As the rain soaks into the ground, so pray the Lord to let his gospel soak into your soul." Charles Spurgeon
