From Spurgeon’s sermon “Christ Precious to Believers”
…he who really has this high estimate of Jesus will think much of him, and as the thoughts are sure to run over at the mouth, he will talk much of him. Do we so? If Jesus is precious to you, you will not be able to keep your good news to yourself; you will be whispering it into your child’s ear; you will be telling it to your husband; you will be earnestly imparting it to your friend; without the charms of eloquence you will be more than eloquent; your heart will speak, and your eyes will flash as you talk of his sweet love. Every Christian here is either a missionary or an impostor. Recollect that. You either try to spread abroad the kingdom of Christ, or else you do not love him at all. It cannot be that there is a high appreciation of Jesus and a totally silent tongue about him.
