Ques 2: I grew up with religion in my life.. My parents bought me up in another church and I was baptised in the LDS church when I was 18. Since then I have come to realise that there have been many challenges in my life I would not have got through without my faith and the support I have had from the church, through the priesthood and the leaders. I can't imagine my life without it. Ques 3: I think the challenges of any religion depend on what trials or addictions people have.. For instance those who smoke may find it more of a challenge adhering to the word of wisdom than those who don't. This is just 1 example.. but there are many more.. Different people struggle with different aspects of the church , but there is always help for those who need it. I hope this helps.:)
