Christians: What does the Bible have to say about witnessing to people of other religions? (Christians only, please.)
This is a Bible question more than a religion question. I realize that many people (especially non-Christians) don't approve of any type of proselytizing and that point of view is duly noted by this asker so there is no need to use this question as a platform to "expound" on that. :) For this question, I'm only interested in specific Bible passages that address how a believer should approach witnessing opportunities in regards to peoples of other religions.
Sadly, most Bible believing Christians these days don't seem to know their own Bibles, so this question may be difficult for most to answer. I have a few specific passages of my own in mind, but I'm curious as to what other believers have to offer to this topic.
Thanks in advance. :)
