But in order to do this, constant watchfulness is necessary and earnest supplication before God to be kept from the evil tendency of this degenerate age to advantage self at others’ disadvantage. You are in a hard place to advance in the divine life. You have a principle, but you do not hang all your weight upon God. You trust too much in your own feeble strength. You have great need of divine aid, of a power not to be found in yourself. There is One to whom you can go for counsel, whose wisdom is infinite. He has…
"And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God."
