You cannot equate things you know with things you believe.
I know that I had pasta for supper last night because I saw it and ate it. But if I tell you that I had pasta last night, then you have to choose to believe me or not to believe me. You werent there and didnt see it.
No do not choose to believe you or not.
I can choose to argue with you or not.
I can choose to contemplate whether what you're saying is true or not.
Most likely I will just nod to it and move on in the conversation.
That doesn't mean I believe it.
In order for me to really believe it I must be persuaded it is true.
I may be persuaded it is true because it has come into my obsevation that you are an honest person.
I may be persuaded it is true because it makes not since for you to lie about such a thing.
But I cannot choose to believe it. I must be persuaded.
Try believing that you don't exist. CHOOSE to believe that you don't exist.
You cannot do it. Why? Because faith is not a choice.
