This scholarly book, containing select writings, engages proactively with Muslims and diverse themes in Christian-Muslim relations in India and elsewhere. It points out that Christians and Muslims can live together in peace and contribute to justice inspired harmony only if they both remain faithful to their moral obligation to give reasonable account of their faith to others. In other words, Christians and Muslims should remain faithful to 'mission' and 'd'awa' respectively. The book affirms that any effort for mutual relationship between Muslims and Christians that does not give sufficient attention to the 'witness-dimension' of their faiths is bound to be either superficial or ephemeral.
