Some of you have posted some great questions and some of you have posted great answers. Ravyn- thank you for clarifying the difference between LDS and the other demonination (didn't think of that).
First let me try to answer or comment on the following questions/comments posted in order.
I will try to keep this short and not bore you guys.
Some people asked why missionaries would come knocking on doors. That is a good question and to be honest, that was one of the hardest parts of my mission- having to go up to a stranger's home and knock on their doors to share the gospel with them IF INTERESTED. I am NOT the type of person that like to walk up to a stranger and start up a conversation- I am pretty SHY with hearing people.
Basically, we do this because this is is a good way to get the information out. HOWEVER, we are taught as LDS missionaries to respect people's wishes regarding religions and lifestyles so if a person is not interested, we will respect that. Some people do not know where to go to find out more info about various churches, or are too shy (right word to use??) to go out seeking so some people feel more comfortable learning more about the gospel in their homes. It depends on the person. We DO have other ways of sharing the gospel with others besides tracting and we use those too. For example, people come visit our temples (located all over) and often would leave contact information if they want further info and we'd follow up on that, some people are referred to missionaries by other people who think they might be interested in learning more, etc.
I'd say the majority of missionaries (LDS) do TRY to respect people's wishes. I apologize to the people who have had bad experiences with representatives of LDS church. Please remember that each missionary is different. There are good and bad missionaries for all churches.
We do NOT believe in forcing beliefs on others or telling others what to do. We believe in sharing the gospel with these interested THEN challenge them to pray about what they have learned and ask if it's the truth.
Now, another post I'd like to make a comment on is the one about missionaries riding bikes. It depends on what mission the person is called to and the location. For the majority of missionaries, they get around by riding bikes (most common since the MAJORITY of missionaries are "poor" because we live on a fixed income during our missions
), walking, taking buses, metro, etc..
I was called to the LDS American Sign Language mission which meant I was to share the gospel with mostly deaf people who signs and as you can guess, deaf people do NOT live next door to each other!
During my whole mission, I and my companions drove a car around to meet with deaf people at their homes.
Hope this clarifies why LDS missionaries do some things the way they do.
Basically, we are all sisters and brothers (no matter what kind of background we come from) and we should all love and respect each other and try to get along..
