spiritual maturity has four particular expressions, each distinct but interdependent on the others: Wisdom: a mature Christian has a heart and mind informed by the truth, largely through the witness of the Scriptures. Good work: a mature Christian has clarity about his or her calling—with the courage and humility and capacity to fulfill this vocation. Ability to love others: a mature Christian knows how to love others in Christ as Christ has loved us. Joy: a mature Christian lives with a deep and resilient joy, even in the midst of a fragmented world.
