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?
