You cannot preach conviction of sin unless you have suffered it. You cannot preach repentance unless you have practiced it. You cannot preach faith unless you have exercised it. True preaching is artesian; it wells up from the great depths of the soul. If Christ has not made a well within us, there will be no outflow from us.
Charles SpurgeonHold everything earthly with a loose hand, but grasp eternal things with a death-like grip
Charles SpurgeonAvoid 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
