Want to know how strict a particular Islamic society is? Just look at the women.
During my time in Southeast Asia, I met many young Muslims who were clearly not practicing Islam as historically prescribed. They were also doing things that are clearly listed as sins in Islam - sex before marriage, getting drunk, dressing immodestly, etc. Normally, the last thing to go, interestingly enough, was eating pork. I always say that it would make more sense to me to start with pork and work my way up, but I guess that's just me.
It's important for us to realize their incredibly difficult situation. There is no guarantee in Islam you can be forgiven even if you are perfect from today forward. Additionally, legalism has little power for inward transformation. So this idea in the gospel that you can KNOW you're forgiven is extremely attractive. I've literally seen people risk their lives for it. Personally I've never felt the gospel so relevant and palpably freeing as I have while sharing with Muslims.
I'm linking to the article below to provide some insight from a young lady desperately clinging to her Islam even though she knows Islam rejects her. For those of you who are familiar with postmodern attempts to believe whatever they want and Christianity at the same time (a la the Emergent church), it may interest you to see a postmodern attempt to do the same with Islam. It just doesn't work and the attempt is sad to witness.
This article was posted on Facebook by a young Muslim girl I know. She's a friendly young woman who identifies with the writer. She's also trying to reconcile who she is with Islam. Please pray for my friend and for the writer as you read. Pray that she will remember the gospel she heard years ago through a student ministry and pray that she will believe. Also, pray for the millions of young Muslims throughout the world who don't know the grace of Christ and whose only choices seem to be radical legalism on the one hand and outright liberalism on the other.
