“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 was a British politician, philanthropist and a leader of the movement to abolish the slave trade. A native of Hull, Yorkshire, he began his political career in 1780 and became the independent Member of Parliament for Yorkshire and a close friend of Prime Minister William Pitt the Younger.
In 1785 he underwent a conversion experience and became an evangelical Christian, resulting in changes in his lifestyle and in his interest in reform. In 1787 he came into contact with Thomas Clarkson and a group of anti-slave trade activists, including Granville Sharp, Hannah More and Lord Middleton. They persuaded Wilberforce to take on the cause of abolition; and he soon became one of the leading English abolitionists, heading the parliamentary campaign against the British slave trade until the eventual passage of the Slave Trade Act in 1807.
