A friend has asked me this question: How is it that someone who lives a good and moral life will go to Hell while another person who has lived a very sinful life, but repents at the last moment, will go to Heaven? Can you help me know how to explain the answer?

The safest road to hell is the gradual one—the gentle slope, soft underfoot, without sudden turnings, without milestones, without signposts. — C. S. Lewis
