And unto one he gave five talents, to another two, and to another one; to every man according to his several ability; and straightway took his journey. – Matthew 25:15

You very often hear men speak of one another as if God had made no mental differences at all. One man finds himself successful, and he supposes that if everyone else could have been as industrious and as persevering as himself, everyone must necessarily have been as successful. You will often hear remarks against ministers who are godly and earnest men, but who do not happen to have much attracting power, and they are called drones and lazy persons, because they cannot make much of a stir in the world, whereas the reason may be that they have but little talent and are making the best use of what they have, and therefore ought not to be rebuked for the littleness of what they are able to accomplish. It is a fact, which every man must see, that even in our birth there is a difference. All children are not alike precocious, and all men certainly are not alike capable of learning or of teaching. God hath made eminent and marvelous differences. We are not to suppose that all the difference between a Milton and a man who lives and dies without being able to read has been caused by education. There was doubtless a difference originally, and though education will do much, it cannot do everything. Fertile ground, when well-tilled, will necessarily bring forth more than the best tilled estate the soil of which is hard and sterile. God has made great and decided differences; and we ought, in dealing with our fellow-men, to recollect this lest we should say harsh things of those very men to whom God will afterwards say, “Well done, good and faithful servant.” – C.H. Spurgeon
