How great is this cause that we don’t need to disagree with any believersIf someone shows interest there is a good reason to spend time on it. If I bring up the Baha’i Faith and receive a negative or dismissive response I make one atempt to proved a prospective to address the issue and then cut and run to the next one. Sometimes it’s best to just make mention of Baha’u’llah and let Him spark an interest in a person if they are receptive. I have only ever been attracted to the writings and have only once or twice met a Baha’i that could present the faith accurately.
What attracts one person may not attract another. For someone hearing Bahá’u’lláh is the return of Christ could be a deal breaker, but may become a Bahá’í eventually after learning about children’s classes and how children are being taught virtues and slowly being eased into religious prophecies. Open mindedness is key in effective teaching, prayer, and deepening. This is just my understanding though.
