They are both from different countries and have never heard of the true message. I don't even know where to start. I just want to share Jesus with them but their backgrounds of god are so different from mine and I don't know where to start.

There was a business in Atlanta with which I used to do business. There was a young man there who was on fire for Islam. We would talk. He knew I was a believer in the Lord Jesus. He invited me to come to his Masjid. I respectfully declined. He would ask me to come each time I was at his place of business. I'd say no, thanks. He got pushy, asking me 'what are you afraid of,' comments like that. It got so that I didn't look forward to going there, although it profited me to do business with them. Finally, I cut ties. I wasn't interested in Allah or Muhammad; I didn't need to do any research on them.
I think the many christian worship centers are open to all who want to hear the gospel preached. You don't have to be invited to a place of worship.
Many people think of their worship the way they do their medical history; it's a private matter and is nobody else's business. I respect that. I didn't invite that young man to come to worship services with me. He knew where the church was located. The only way I learned he practiced Islam was that he told me. Then he asked if I was a person of faith. (I think he suspected I was because of a lot of things. There's usually something noticeable about a conscientious man). I said I followed the teachings of the Christ, and he set out on a mission to get me to reexamine my life. (Yes, that's what you're asking a person who already practices a faith to do. It can be annoying, not to mention it can make the proselytizer look arrogant.
