Spurgeon Quote

I came across this quotation from Spurgeon in the latest Banner of Truth magazine. I think it may be valuable for some on this forum

"Be well instructed in theology, and do not regard the sneers of those who rail at it because they are ignorant of it. Many preachers are not theologians, and hence the mistakes they make. It cannot do any harm for the most lively evangelist to be also a sound theologian, and it may often be the means of saving him from gross blunders. Nowadays we hear men tear a single sentence of Scripture from its connection, and cry "Eureka! Eureka!" as if they had found a new truth; and yet they have not discovered a diamond but a piece of broken glass. Had they been able to compare spiritual things with spiritual, had they understood the analogy of the faith, and had they been acquainted with the holy learning of the great Bible students of ages past, they would not have been quite so fast in vaunting their marvellous knowledge. Let us be thoroughly well acquainted with the great doctrines of the word of God, and let us be mighty in expounding Scripture."
