J. C. Ryle
Let others, if they will, preach the law and morality; let others hold forth the terrors of hell, and the joys of heaven; let others drench their congregations with teachings about the sacraments and the church; give me the cross of Christ! This is the only lever which has ever turned the world upside down hitherto, and made men forsake their sins. And if this will not, nothing will. A man may begin preaching with a perfect knowledge of Latin, Greek and Hebrew; but he will do little or no good among his hearers unless he knows something of the cross. Never was there a minister who did much for the conversion of souls who did not dwell much on Christ crucified. This is the preaching which the Holy Ghost delights to bless. He loves to honour those who honour the cross.
Whenever a church keeps back Christ crucified, or puts anything whatever in that foremost place which Christ crucified should always have, from that moment a church ceases to be useful. Without Christ crucified in her pulpits, a church is little better than a cumberer of the ground, a dead carcase, a well without water, a barren fig tree, a sleeping watchman, a silent trumpet, a dumb witness, an ambassador without terms of peace, a messenger without tidings, a lighthouse without fire, a stumbling-block to weak believers, a comfort to infidels, a hot-bed of formalism, a joy to the devil, and offence to God.
