Continuing from a previous post, Timothy Keller from his book ‘The Reason for God’ taught:
Christianity not only leads its members to believe people of other faiths have goodness and wisdom to offer, it also leads them to expect that many will live lives morally superior to their own. Most people in our culture believe that, if there is a God, we can relate to him and go to heaven through leading a good life. Let’s call this the “moral improvement” view. Christianity teaches the very opposite. In Christian understanding, Jesus does not tell us how to live so we can merit salvation. Rather he comes to forgive and save us through his life and death in our place. God’s grace does not come to people who morally outperform others, but to those who admit their failure to perform and who acknowledge their need for a Savior.
Christians, then, should expect to find nonbelievers who are much nicer, kinder, better than they are. Why? Christian believers are not accepted by God because of their moral performance, wisdom, or virtue, but because of Christ’s work on their behalf. Most religions and philosophies of life assume that one’s spiritual status depends on your religious attainments. This naturally leads adherents to feel superior to those who don’t believe and behave as they do. The Christian gospel, in any case, should not have that effect.
It is common to say that “fundamentalism” leads to violence, yet as we have seen, all of us have fundamental, unprovable faith commitments that we think are superior to those of others. The real question, then, is which fundamentals will lead their believers to be the most loving and receptive to those with whom they differ? Which set of unavoidably exclusive beliefs will lead us to humble, peace loving behavior?~ Timothy Keller, The Reason for God (New York, NY: Penguin Books, 2008, 2018), 19-21
