Todd Johnson and Charles Tieszen, writing in the Evangelical Missions Quarterly, emphasised the importance of Christians to have contacts with non-Christians as their study showed that 86 percent of all Hindus, Muslims and Buddhists do not know a Christian.
Johnson and Tieszen wrote God Himself is our model when it comes to Christians making personal contact with their non-Christian counterpart. Given the minimal contact between Christians and people of other faith, both authors believed Christians should take the initiative to deliberately make contact or befriend them so the cause of Christ can be advanced.
Reviewing the article, Natalie Crowon, a research assistant at the Centre for the Study of Global Christianity at Gordon-Conwell Theological Seminary, wrote in the Lausanne World Pulse publication that the finding in this article had implored Christians worldwide to evaluate its method of evangelism, both in individual and group level, so that energy and resources could be allocated to those who had little chance to know God.
"Each of these findings indicates that the global Christian community has been measured and found wanting," she wrote.
"The research implores us to consider our own methods of evangelism both on individual and group levels."
However, she sounded a caveat to Christians about evangelising people of other faith, saying that any methods used to reach them should be rooted in love and compassion for the sake of Christ.
