I let them talk and invite me to their Easter worship service. If I am correct, they don't celebrate holidays, but they do like to encourage people at this time of year to focus on the Savior, and not on the Easter bunny. I almost told them that my Sundays are so busy that I don't have time to go to their service! lol Instead I just told them that I have my own religion.
They offered me some literature, but I told them I wasn't interested. I hesitated at first in saying this, but finally I just told them that I had been offered some of their literature before that gave information about my religion. I had taken it, and read through it, but was disappointed to find that they had published incorrect things about our beliefs. My thinking is that if you are a church, representing the Savior, then you should work very hard to make sure that everything you do, say, and print, is the truth. And never should you intentionally do, say, or print something that you know to be false, even if you feel the ends justify the means. In this case, I think that the people who printed that information just didn't understand our beliefs. So I told them that I really had no interest in reading their information, and that frankly I had plenty of my own religious information to read. :)
But I did go on to tell them that I appreciate what they are doing. I appreciate that they take the time to testify. I may not agree with all of their beliefs, but I do understand the need to testify to others. I told them that I served a mission in Taiwan, as did my husband. I told them that two of my children are currently serving. But I like that they devote much of their time on a regular basis to testifying.
As they were leaving, one of them noticed a car that is sitting unused in our driveway, and expressed an interest in buying it. I may not have gotten much out of our religious conversation, but I might get a car sale out of it! lol But my advice to you is that whenever you have representatives of any religion come to your door, be nice to them and remember that they are doing this because of their love of God! :)
