Emotional spirituality is an emotional maturity and spiritual maturity that go hand in hand. It's simply not possible to become spiritually mature while you remain emotionally immature. Emotional maturity really boils down to one thing: love. So if you're critical, defensive, touchy, unapproachable, insecure—telltale signs of emotional immaturity—you can't be spiritually mature. Love is that indispensable mark of maturity.
