Yes, God can do all that He wills.

"Then Job replied to the Lord:
'I know that you can do anything,
    and no one can stop you.'"
-Job 42:1-2 NLT

"All the people of the earth
    are nothing compared to him.
He does as he pleases
    among the angels of heaven
    and among the people of the earth.
No one can stop him or say to him,
    ‘What do you mean by doing these things?’"
-Daniel 4:35 NLT
