Most of the grand truths of God have to be learned by trouble; they must be burned into us with the hot iron of affliction, otherwise we shall not truly receive them.
Charles SpurgeonYou 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 Spurgeon
