I'm sorry to say that if you pray "Your Kingdom come and will be done," then you are inviting discomfort. There's no other way to grow, no other way to see His Kingdom realized in a human life.
We must be careful, though. It's not just any discomfort. It's the Spirit-guided one we're after, the one that lead Jesus to a desert. This type of discomfort always brings greater life, joy, peace and intimacy with the Father (if you wanted a litmus test, look for that stuff at the end).
So I'm not inviting you into masochistic pain-seeking — that's not Christian. I just mean to remind you that your journey will include discomfort. No good parents spare their kids every pain in life and neither does our good Father in Heaven. But we can trust that all of His activity in our lives is good for us and brings Him glory.
