Holding onto God's promise in real life

I read on a pastor's blog an observation. That when reading God's word, especially those super awesome exciting promises of the coming Kingdom, of a world with out pain, of eternal life and boundless hope, moments like those makes me feel like I'm already in paradise! But when I put down the bible and get back to real life, I am reminded of all the crap. Financial debt, broken family, constantly struggling with myself emotionally, struggling to love other people, struggling with critical attitude and bitterness towards some people... man, how does God's promises translate into real life? Why the disconnect?
