Start With Christianity
For those unacquainted with religions, it is often thought by them that all religions are basically the same. After all, every religion offers peace of mind, moral teaching, a connection with the divine, and a means for prayer, ritual, and worship, leading to meaning, fulfilment, and happiness.
To the unacquainted, religion sounds like one of life’s optional extras. It is particularly suited to those who are not scientific, easily intellectually satisfied with mystical answers, and probably already familiar with religion due to their upbringing.
