i can't speak for wishful thinker - and cannot even prove what i am saying is true. you have to experience it for yourself. but, as wishful thinker is pointing out - it is unlikely you will experience God in the many forms He can take (whether miracles/answers to prayer, direct contact in some way, or indirect - through other people saying and doing things at just the right moment to encourage you) if you express doubt.
the good thing is - that even the disciples had doubt. peter was walking on water - but suddenly looked down at the water instead of at Jesus. the way things appear is not always the way they 'are.' we think they 'are' because of our understanding of science. but, what if God can undo anything scientific to fit the bill of 'miracle.' to defy a natural law for the sake of helping someone's faith. for instance - to make the sun stand still. to allow strange phenomenon that have previously not been seen (plagues of egypt - so many years ago, and various problems we see today that are 'unusual'). gideon and his wet/dry cloth experience. Jesus Christ casting out demons, walking on water, changing water to wine, forgiving and helping lepers/diseased people be cured.
i believe we will all see more and more unusual phenomenon as God reveals Himself and his word true. if you believe or don't believe - it's really only affecting yourself. your own future. i mean - we can positively affect others by relaying what has happened in our own lives and encouraging them to be open to God. but, it all depends on what we each personally do with the information.
for instance - you can be satisfied that you are sure 'there is no God.' but, isn't that being closed minded if you happen upon a situation where there was a 99-1 chance that this was not chance happening - but a true miracle? where do miracles fit into non-belief? they don't. you can't explain them - but they exist. i know this for a fact myself. an absolute fact. could i prove it unless i was with someone and another miracle happened- probably not.
but, faith isn't just seeing. faith is believing without seeing first. that is why Jesus said 'blessed are those who haven't seen me, and yet believe.' thomas actually saw the wound in Jesus side and the nail holes in his hands. we have to wait to see the ressurrected Jesus. and yet, he gave us the Holy Spirit as a comforter. if you want to test the spirits - test and see if baptism does not bring you joy, peace, happiness, love - and those elements that are 'spiritual' and not 'chemical.' how can one be happy when everything is seemingly going wrong in one's life. there are christians that you can meet that have had terrible experiences, lives - and they do not become broken or feel badly. why is this so? i think it is because God gives us energy like no other. you can't bottle it. it's free, too. it is like a calling card to God's hotline. any problem you know you can get solved - so you just don't worry.
because of having faith - you worry less and more positive things come into your life. you can't help but be blessed when God is for you. abraham was one of the most blessed men on earth. God started just giving him things. but not before he tested him severely.
