Knowledge

Knowledge is only potential power. Knowledge is power only when put to use – and then only when the
use made of it is constructive.

Lord!

Lord, thou knowest that no strength, wisdom or contrivance of human power can signify, or relieve me. It is in thy power alone to deliver me. I fly to thee for succor and support, O Lord let it come speedily; give me full proof of a thy Almighty power; I am in great troubles, insurmountable by me; but to thee slight and inconsiderable; look upon me O Lord with compassion and mercy, and restore me to rest, quietness, and comfort, in the world, or in another by removing the hence into a state of peace and happiness. Amen.

William Wilberforce, Real Christianity

“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.”
