The Character of Christ
"Today many assume that spiritual maturity is measured by the amount of biblical information and doctrine you know. While knowledge is one measurement of maturity, it isn't the whole story. The Christian life is far more than creeds and convictions; it includes conduct and character. Our deeds must be consistent with our creeds, and our beliefs must be backed up with Christlike character." - Warren, Rick. "The Purpose Driven Life."
"...the change which demonstrates higher maturity actually involves an internal transformation which makes us become more like God Himself... The goal of our spiritual growth, then, is to become a person whose character actually matches up with God's." - Davis, Freddy. “Spiritual Maturity Handbook.”
“Spiritual formation into Christlikeness—true change of character—comes from living in relationship to God.” - Willard, Dallas. "Hearing God: Developing a Conversational Relationship with God."
