The worth and excellency of a soul is to be measured by the object of its love.--Henry Scougal, The Life of God in the Soul of Man (Christian Focus, 1996; repr.), 68. Scougal was professor of divinity at Aberdeen till his death in 1678 at age 28 of tuberculosis. This little book was a letter he wrote to a depressed friend in 1677. A century later, John Wesley sent a copy of the letter to a friend of his named George Whitefield. Whitefield later said that this letter was instrumental in his conversion--'I never knew what true religion was till God sent me this excellent treatise.'
The images of these [noble and well-placed loves] do frequently present themselves unto the mind, and by a secret force and energy insinuate into the very constitution of the soul, and mold and fashion it into their own likeness: hence we may see how easily lovers and friends do slide into the imitation of the persons whom they affect . . .
The first sentence in the above quote is worth the price of the book. What do you love? That's what you will eventually look like.
