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?
Timothy KellerThe Christian gospel is that I am so flawed that Jesus had to die for me, yet I am so loved and valued that Jesus was glad to die for me.
Timothy KellerOn the cross Jesus was treated as an outcast so that we could be brought into God's family freely by grace.
Timothy KellerThe most rapturous delights you have ever had - in the beauty of a landscape, or in the pleasure of food, or in the fulfillment of a loving embrace - are like dewdrops compared to the bottomless ocean of joy that it will be to see God face-to-face (1 John 3:1-3). That is what we are in for, nothing less. And according to the Bible, that glorious beauty, and our enjoyment of it, has been immeasurably enhanced by Christ's redemption of us from evil and death.
