The man who does not make hard work of his ministry will find it very hard work to answer for his idleness at the last great day. A gentleman who wants an easy life should never think of occupying the Christian pulpit, he is out of place there, and when he gets there the only advice I can give him is to get out of it as soon as possible; and if he will not leave the position voluntarily, I call to mind the language of Jehu concerning Jezebel, Fling her down, and think the advice applicable to a lazy minister. An idler has no right in the pulpit. He is an instrument of Satan in damning the souls of men.
The ministry demands brain labour; the preacher must throw his thought into his teaching, and read and study to keep his mind in good trim. He must not weary the people by telling them the truth in a stale, unprofitable manner, with nothing fresh from his own soul to give force to it. Above all, he must put heart work into his preaching. He must feel what he preaches: it must never be with him an easy thing to deliver a sermon; he must as if he could preach his very life away ere the sermon is done. There must be soul work in it, the entire man must be stirred up to effort, and the whole nature that God has endowed him with must be concentrated with all its vigour upon the work in hand. Such men we want.
To stand and drone out a sermon in a kind of articulate snoring to a people who are somewhere between awake and asleep must be wretched work. I wonder what kind of excuse will be given by some men at last for having habitually done this. To promulgate a dry creed, and go over certain doctrines, and expound and enforce them logically, but never to deal with men’s consciences, never to upbraid them for their sins, never to tell them of their danger, never to invite them to a Saviour with tears and entreaties! What a powerless work is this! What will become of such preachers? God have mercy upon them! We want labourers, not loiterers. We need men on fire, and I beseech you ask God to send them.-C.H. Spurgeon
