The key to happiness, fulfillment, and salvation is becoming the person God intended you to be. God has a plan for your life, and that plan calls for you to grow up. No, we are not talking about being old enough to vote and sign contracts. We are not talking about increasing in height or weight. And we are not talking about getting married and having children or any of the other outward trappings of adulthood.
Spiritual maturity is about your heart being transformed to become more and more like Jesus. Jesus is the model for what grown-up men and women should be like, and we want to become more like Him.
