But we rebel against the impossible. I sense a wish in some professional religion-mongers to make God possible, to make him comprehensible to the naked intellect, domesticate him so that he's easy to believe in. Every century the Church makes a fresh attempt to make Christianity acceptable. But an acceptable Christianity is not Christian; a comprehensible God is no more than an idol. I don't want that kind of God. — Madeline L'Engle.
Only if your God can say things that outrage you and make you struggle will you know that you have gotten hold of a real God and not a figment of your imagination. — Timothy Keller, The Reason for God.
