Here are great quotes by William Wilberforce.

“Is it not the great end of religion, and, in particular, the glory of Christianity, to extinguish the malignant passions; to curb the violence, to control the appetites, and to smooth the asperities of man; to make us compassionate and kind, and forgiving one to another; to make us good husbands, good fathers, good friends; and to render us active and useful in the discharge of the relative social and civil duties? ”― William Wilberforce

“Selfishness is one of the principal fruits of the corruption of human nature; and it is obvious that selfishness disposes us to over-rate our good qualities, and to overlook or extenuate our defects.”
― William Wilberforce

“Let him then, who would be indeed a Christian, watch over his ways and over his heart with unceasing circumspection. Let him endeavour to learn, both from men and books, particularly from the lives of eminent Christians, what methods have been actually found most effectual for the conquest of every particular vice, and for improvement in every branch of holiness. Thus studying his own character, and observing the most secret workings of his own mind, and of our common nature; the knowledge which he will acquire of the human heart in general, and especially of his own, will be of the highest utility, in enabling him to avoid or to guard against the occasions of evil: and it will also tend, above all things, to the growth of humility, and to the maintenance of that sobriety of spirit and tenderness of conscience, which are eminently characteristic of the true Christian.”
― William Wilberforce

“Let true Christians then, with becoming earnestness, strive in all things to recommend their profession, and to put to silence the vain scoffs of ignorant objectors. Let them boldly assert the cause of Christ in an age when so many, who bear the name of Christians, are ashamed of Him: and let them consider as devolved on Them the important duty of suspending for a while the fall of their country, and, perhaps, of performing a still more extensive service to society at large; not by busy interference in politics, in which it cannot but be confessed there is much uncertainty; but rather by that sure and radical benefit of restoring the influence of Religion, and of raising the standard of morality.”
― William Wilberforce

“Why is it so hard to get people to study the Scriptures? Common sense tells us what revelation commands: ‘Faith comes by hearing, and hearing by the word of God’–‘Search the Scriptures’–‘Be ready to give to every one a reason of the hope that is in you.’ These are the words of the inspired writers, and these injunctions are confirmed by praising those who obey the admonition. And yet, for all that we have the Bible in our houses, we are ignorant of its contents. No wonder that so many Christians know so little about what Christ actually taught; no wonder that they are so mistaken about the faith that they profess.”― William Wilberforce

“In the calmness of the morning before the mind is heated and weary by the turmoil of the day, you have a season of unusual importance for communing with God and with yourself.”― William Wilberforce
