Charles H. Spurgeon on Psalms 96:3

Declare his glory. It is his glory which should be proclaimed, not the learning, ability, and eloquence of the orator who professes to speak for Him; it is his glory, the loving beauty, the attractiveness of his gospel, the lavish promises to repentant sinners, the blessedness of heaven, which should be the chief themes of discourse; not threats, menaces, sermons on hell or torment to affright men, and at best make them God's trembling slaves, not his loving friends. The preaching is to be unto all people, in obscure country districts, amongst unpolished and illiterate congregations, and not to be confined, as fashionable preachers like to confine it, to the cultivated and critical audiences of the capital. Hugo, quoted by Neale and Littledale.
