I played soccer with a guy in high school who was a Mormon. I ended up going to his (false) church almost every Wednesday night for basketball. We occasionally would have to do something else, like sit through a service, go feed the poor, or do an activity. One of the activites was set up so that we got fake money and could use it as we pleased. I tried to buy a game with it, and got sent to one of the kingdoms that was not 'celestial' as a result. So that's when they explained the three levels of heaven. My buddies were all more or less on the rebellious side of the church, though they all went on mission trips. They listened to music they weren't supposed to, etc.Anyway, I ended up playing in bands with them, and stayed in touch with them. After I was converted, and ended up seeing less of them. One of them called me and asked me to play in his band. I explained that I had been converted, and didn't want to play in a band that didn't have a clear gospel message. I didn't confront him with his sin, but I did explain that I had researchedhis and basically all religions. We said we would talk again, but I never heard back from him.I sent an email right after I was converted to one of the other guys, explaining what had happened, and he basically ignored it, even though we corresponed all the time. Pray that I would have the courage to reach them all one by one, as I have not made a particular effort to do so.Here is the deal, by human standards, Mormons can by extremely good and nice people. One of the families let me (an outsider) hang out with their son the night before he left for his mission, which was a no no. Many of the families were friendly with me, and knew me by name, invited me to spend the night, invited me to Bible studies, Friday night activities, etc. One of the reasons I liked hanging out with them before I became a Christian was that they weren't into drugs, alcohol, profanity, etc.Like any other religion, the majority stay within the Mormon faith for the same reason most people go to churches that are Christian; because momma did (or something similar). The average Mormon that I know, even though they learned other languages to go on missions, know all the doctrine, marry within the faith, is not necessarily zealous. Like most of our churches, they just get you involved within the fellowship, and hope you 'get into it.'I hung out with them for years, and no one ever tried to whole-heartedly convert me. But how often does this happen within our churches? So realize they are just people, and really just need to be confronted with their sins like anyone else.Here is a tract from Chick that goes through an encounter between Mormons and a Christian. Shows how they believe God is a normal man, lives near the star 'Kolob', they believe dark skin shows that the individual is not a valiant spiritual warrior, they believe Jesus and Satan were spirit brothers, they have doctrine related to the occult:http://www.chick.com/reading/tracts/0061/0061_01.aspI have heard Mormons speak in tongues, have ceremonies for baptism of the dead, wear undergarments after reaching certain statures, etc. If the guys I knew did these things or knew of them, they never talked to me about it.
