Holiness
“Every man is as holy as he really wants to be.”

Man: the Dwelling Place of God, 40

“What does this word holiness really mean? Is it a negative kind of piety from which so many people have shied away? No, of course not! Holiness in the Bible means moral wholeness– a positive quality which actually includes kindness, mercy, purity, moral blamelessness and godliness. It is always to be thought of in a positive, white intensity of degree.”
I Call it Heresy, 63

Holiness of God
“We cannot grasp the true meaning of the divine holiness by thinking of someone or something very pure and then raising the concept to the highest degree we are capable of. God’s holiness is not simply the best we know infinitely bettered. We know nothing like the divine holiness. It stands apart, unique, unapproachable, incomprehensible and unattainable. The natural man is blind to it. He may fear God’s power and admire His wisdom, but His holiness he cannot even imagine.”
The Knowledge of the Holy, 111.
