Yes she was. And when they dated, all the meeting was filled with religion debate. She came from a region with a very thick Islamic culture. My friend came from a region with a very thick Christian culture. And this is the story of the husband (my friend):
Often he thought of breaking up with her (and so did she). But there’s a strange bond between them (no, they didn’t do anything sexually, just talking and sharing and such).
Then one day, out of the blue, his girlfriend asked for a Bible. My friend at first suspicious that she planned to read it so she could attack the Bible but he gave her anyway.
After sometimes, her attitude changed and said she was interested in Christianity and my friend asked why (because due to his effort to convince her through debates, she was very much unconvinced, and even tried to convince him back about Islam). Then she told my friend that at one night, she did Tahajud, and at that moment, suddenly there’s something in her heart that she prayed for Allah to show the true way and give her a sign. Suddenly, she saw a bright red cross sign on her sajadah.
After that, she became confused, that’s why she asked a Bible to my friend.
When she became a Christian, it was at first a disaster. She was locked by her family and my friend had to flee from that region, if not he would probably have been a history by now. But my friend gave his address to her and soon afterwards she ran away too and they got married.
The story ended happily (the sad thing, she was disowned by her family). They got married, and at the time I met this friend, they had a baby boy. Too bad, I haven’t had time to meet his wife, because I met this friend when he got a scholarship to study, and left her at home. But he did show me a lot of photos of the happy couple.
