You decide that health is really important to you and you let the universe know that you are ready to achieve a state of good health. The next thing you know, you get into a car accident and end up in the hospital.
The faith based way doesn't sound too appealing to me.
I think if my affirmations were being answered in this way I'd have to ask "what exactly am I putting out there that is attracting this???" Then I'd change my affirmations!
Come to think of it, this sounds like how my life used to go before I was more conscious of these things.
