Romans 9:16-20

So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.

For the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth.

Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.

Thou wilt say then unto me, Why doth he yet find fault? For who hath resisted his will?

Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus?
