It's not acceptable to manipulate people by charity aids, at least, it's not honest.. and I guess you won't approve it either...
You are corrrect. I don't believe in manipulation or bribery as a tool to convert people. Nor do I believe in threats as a tool to keep people from converting.
But, If you were really convinced about your religion, you won't make use of these indirect tools to turn people from their true religion.
The use of indirect tools is harder to both control and measure. Christians should not, as I said above, be trying to manipulate people. On the other hand, in my own church, we throw parties and have celebrations for the children who attend here. We don't tell them that they cannot bring their friends. We support the needs of members who may be haivng a hard time financially or dealing with other personal crisis. Doing these things might make us seem more attractive to people, but we don't do them to make ourselves attractive, we do them to meet the real needs of our members. Beyond that, we also respond to emergency situations around the world. We are presently responding to wildfires in our own country that burned thousands of people out of their homes. We responded when Katrina devestated a different large portion of our country. We are responding to needs in other countries for things like mosquito nets to help combat malaria. And we have responded to famines, floods, and earthquakes in many places around the globe. These things are not sent with strings attached. I know this because, through a curious bit of irony, my own daughter was a recipient of such aid when her hometown was struck by a terrible earthquake.
My daughter is a Muslim, living in a Muslim country. The supplies that helped her get through the winter came in crates with the initials UMCOR stamped on them. Those who delivered them did nothing more than deliver the aid and assist them in distributing it. My daughter and her whole family continued to practice their faith undisturbed. She didn't know anything about who or what UMCOR was, only that they were somehow connected with churches back in the USA, and she knew that because her father is mayor of the town and things were coordinated through him to make sure the aid got where it was most needed. (I probably need to explain, that I am not referring to my biological daughter, but an exchange student who has become my daughter. She is native Turkish girl who came to live with me later as an international exchange student for a short time about a year after these earthquakes. Because of the closeness of our continued relationship, though back with her own family now, she still calls us Mom and Dad, and we still consider her to be our daughter -- as we do with all of the students who have lived with us over the years.) It was only after she came to live with us that in conversation about those quakes she showed me some pictures and I noticed the UMCOR logo that was stamped on a few crates. I asked about it and that's when she told me about them. She said that she wished she could express her gratitude to those who had given them, and I was able to inform her that it was in fact our church and hundreds others that had joined together to make them available. But not once at the time that she received the aid, or later when living with me did anyone suggest to her that we sent it for any other purpose than simply to meet human need. She was a Muslim before she came to live with me; I did nothing to try to convert her while she lived with me (a promise I made to both myself and her, for while I believe in sharing the gospel, I do not believe that anyone should feel compelled against their will and living with me, a pastor, for a full year might be difficult enough for her, so I did not want that to be hanging over her head as well), and she remains a practicing Muslim today.
Be honest and answer this question by yourself. You won't find any Muslim believing really in other religion than Islam, the example of those 'converts' in Algeria is expressive...
I'm afraid I don't see a question, just a statement. So, I really can't answer any question to myself or anyone else. But of course no Muslim believes in anything other than Islam. Someone who believed in something different would not be a Muslim, they would be an ex-Muslim.
