Read the book of Job, you of little faith. We do serve a God who performs miracle to those who come to him with a repented heart, and really serve him, and have faith in him. How I know because he has answered many of my prayers, and even done miracles on my behalf. Why? Because I still praise his holy name and worship him as Job did many times in my life. He gave me the strength and courage to face each adversity in my life without me blaming God, but knowing he knows what is better for me than I know myself, and accepting it with faith that he will not give me more than I can take. I still continue to love him with all my heart no matter what, that is faith, not anger at God, nor question why some prayers are not answered. May you come to know the real God of mercy, and then you will be praising him no matter how hard your life may be, because he gives us the grace to do so.
