" Unless we are profoundly certain God is our Father, we will never be able to say “thy will be done.” Fathers are often inscrutable to little children. A four-year-old cannot understand many of his father’s prohibitions—but he trusts him. Only if we trust God as Father can we ask for grace to bear our troubles with patience and grace. "

― Timothy J. Keller , Prayer: Experiencing Awe and Intimacy with God
