“The gospel frees us from the need for people’s approval and adoration so that we can confront and anger the people we love if that is what is best for them. And although it does not always work, this is the only kind of communication that really changes people. If you love a person so selfishly that you cannot risk their anger, you won’t ever tell them the truth they need to hear. If, on the other hand, you tell a person the truth they need , but with harshness and not with the agony of a lover, they won’t listen to it.
But if you speak the truth with lots of love evident at the same time, there is a great chance that what you say will penetrate the heart and heal. A gospel-based ministry is marked by loving honesty, not spin, image and flattery.
This kind of gospel ministry is costly to the minister. It is not always easy for those they are ministering to. But it is based on the truth; it is pointing to Christ; and it is eternally worthwhile. We would do well to imitate Paul in our ministry to others; and to love and thank those who love us enough to minister to us as he did to the Galatians [c.f. Galatians 4:16-20]”
-Timothy Keller (Galatians For You, pp 114-115)
