"A whetstone, though it cannot cut, may sharpen a knife that will."
"If I had any human master he would have been out of patience with me long ago, but the Lord Jesus Christ never gives up a scholar; having once commenced to teach, he continues his divine lessons till they are fully learned, and the more difficult it is for him to teach the more honour it will be when he gets all his scholars educated for the skies."
"He cannot be a disciple who does not learn, but invents."
"It seemed, sometimes, to be rather repelling men than attracting them to say to would-be disciples, 'If you will follow me, do this, and do that,'—perhaps, some very trying ordeal; yet that was the Saviour’s usual habit."
"You cannot be Christ’s servant if you are not willing to follow him, cross and all. What do you crave? A crown? Then it must be a crown of thorns if you are to be like him. Do you want to be lifted up? So you shall, but it will be upon a cross."
"God in his providence and in grace, as far as we have been made willing to learn of him, is educating us for something higher than this world."
"All the flowers of the field, and many of the beasts of the plain, and now the very orbs of heaven, are turned into metaphors and symbols by which the glory of Jesus may be manifested to us. Where God takes such pains to teach, we ought to be at pains to learn."
