Yes, but not all the time.
John chapter 9:
2 And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind?
3 Jesus answered, Neither hath this man sinned, nor his parents: but that the works of God should be made manifest in him.
Sometimes people have problems so that the works of God can be made manifest in them, which means God wants us to witness miracles. It doesn't guarantee a miracle will happen, but, there it is.
