God is the loving heavenly father of us all, He wants us all to get along and to love each other. Despite the differences all religions have all religions have some truth to them, Things that they have in common. This truth although not complete is a great thing and we should seek out this truth, wherever we can find it. These truths that people have have come through faithfully searching of Gods word.
Although other churches do contain truth we believe and teach that there is only one place that the entire truth can be found. And logically not everyone can be 100% correct unless they were all united in their beliefs, and our claim is that the original truth that Jesus Christ taught when he was lost and after centuries of people searching faithfully for it, God restored it through a man called Joseph Smith.
When asked what Mormons believe, Joseph Smith produced a news article that we refer to as the 13 articles of faith. The 11th article is about our belief on religious freedom, that we believe we should worship God how we feel, and that other people should be entitled to this same freedom. Despite the differences of belief we have to other christian denominations we do believe that everyone is entitled to follow God the best way they know how, whatever way of worshiping God it may be. We simply invite others to take the faith in God that they already have and see if what we have can increase their beliefs in God and help them to form a closer relationship with their heavenly father.
Ultimately God will judge each one of us based on what we know and what we did with the knowledge that he has given us. If we have accepted the sacrifice for sin Jesus Christ offered for us and are trying our best to repent of our own individual sins. God expects us to put in the effort and find truth and when we find truth to act on that knowledge.
