God is not a vending machine. You don't just insert a prayer, get what you want, and walk away until the next time. He is our Father, and we have to walk with Him in faith in the good times and the bad times. We only exist because of His Grace. All we have comes from His hands, from the colour of our eyes to the talents we have. Nothing about you is an accident of birth or fate. You were perfectly and purposefully made with a reason.
