Some Christians think they are able to do without constant spiritual effort because they do not heed the urgency of confronting themselves with the truth of the gospel. So as not to disturb their way of living, they attempt to empty, and make innocuous, words such as: “Love your enemies, do good to those who hate you” (Luke 6:27). For these persons such words are difficult to accept and translate into a coherent conduct of life. In fact, they are words that, if taken seriously, demand a radical conversion
