Why is it so hard to do good

Because the pastors and preachers miss the point or they intentionally miss it.Most religions especially the christians teach about love of people,love of God,love of country and so on.But when it comes to morality,they don't touch this subject.You see Jesus commanded the apostles to preach the word of God freely."You receive freely,give it freely."Baptism fee,confirmation fee,marriage fee,and even when you die there is a fee.This fees are immoral because Jesus did not ask for any fee in his entire teaching days.Moreover this religions receive donations from people who are making money out of the sweat of poor people.The corporations and the bankers are examples of this.Even criminals who earned enough money through illegal gamblings are donors for their respective religions.That is why when this kind of people seeks permit to operate their illegal bussiness,these religions are silent and obedient to them.I ask you?will this society produced law abiding and god fearing people.You know the answer.

I can only answer this from my own perspective, but my God doesn't ask me to do anything He doesn't empower me to do. The things He asks is for my good, and for the people around me.

Actually, a lot of the things various religions tell you to do to "get your reward" are also just good ideas for living anyway. Many of them are morals and ethics that those without religions follow as well. It depends on the religion exactly what is required of you to acheive whatever reward is being offered, and it does seem that some are harder than others. Most, however, also offer ways to make up for what has gone in the past, or ways to eradicate its effects on your afterlife altogether. I think if you lived life honestly in ways that are both healthy and enjoyable, you'd find yourself following a lot of the rules of various religions without intentionally doing so. Some of those rules are just common sense and decency. Personally I don't find that my religion asks more of me than I can give, though sometimes it would be easier to live life without its constraints. But then I remember all the really stupid stuff that I've not done, or stopped doing, because I knew it was against the will of my Gods, I know I've made the right choice for me. Note the words "for me" there. I don't think there's one right answer for everyone. There are people who find themselves behaving more ethically and morally after leaving a religion, and being happier as well.
