Life Is Not Fair But God Is?

I was under the teaching and understanding that a life of faith will protect us from the schemes of satan and the curse of the earth found in Genesis 3:17. However, most of us have suffered various things in life and I read in Revelation 22:3 that the curse will not be removed onto the New Jerusalem. That makes much more sense and helps me to understand life on earth in this physical flesh and the devils power and plan. It is a huge mystery and God does bless and protect us but there is a general curse on all of humankind and no one escapes that truth. Our only hope is found in Jesus Christ and that is also difficult but in the end, He conquers and overcomes the curse. What do you think?
