Without the gospel we hate ourselves instead of our sin. Without the gospel we’re motivated through all sorts of awful fear and pride to change and it doesn’t really change our hearts; it just restrains our hearts.
You have inside you the capacity to invest your mental, emotional, and spiritual gifts in a way that glorifies God, impacts the world, and satisfies your own soul. I believe that-and I want you to believe it, too.
You will learn a lot about yourself if you stretch in the direction of goodness, of bigness, of kindness, of forgiveness, of emotional bravery. Be a warrior for love.
Faith in the gospel restructures our motivations, our self-understanding, our identity, and our view of the world. Behavioral compliance to rules without heart-change will be superficial and fleeting… We can only change permanently as we take the gospel more deeply into our understanding and into our hearts. We must feed on the gospel, as it were, digesting it and making it part of ourselves. That is how we grow.
Christians tend to motivate others with guilt. We tend to say: You would do this if you were really committed Christians, indicating that we are committed and all that is needed is for others to become as good as we are! This is why so many churches quench the motivation of people for ministry. In our shoes, Paul would say: Remember the grace God has showered on you—what does living out and enjoying that grace look like in this situation?
