“The proof of spiritual maturity is not how pure you are, but an awareness of your impurity. That very awareness opens the door to grace. Spiritual maturity is not measured in the rules you keep. Spiritual maturity is not measured in the Bible answers you know in small groups. Spiritual maturity is not even about what you do. Primarily, Spiritual maturity is knowing who you are in Christ.” --Philip Yancey, The Jesus I Never Knew
