Romans 9:20-21 says 'But who are you, O man, to talk back to God? “Shall what is formed say to Him who formed it, ‘Why did You make me like this?’” Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use?' Paul is not saying that some of us are worth more than others, but simply that the Creator has control over the created object. So we have no right to criticise anything that our Creator made, the amazing thing is He has freely given us all things because He is LOVE.
This is an amazing picture of all God has done for us and how we have been rescued to walk in the light of Jesus Christ. When Jesus met a man described in Luke 8:30 the man identified himself as 'Legion'.
