As long as we are alive, we will experience the full range of emotions that God created us to feel. Like we have talked about before, all emotions serve a purpose in helping us navigate life safely. If we no longer felt fear, for example, we would be very vulnerable to unsafe people and dangerous situations. So, emotional maturity is not about reaching a place in our personal growth in which we no longer feel negative or challenging emotions.
