Jesus taught that angels can see God. "Take heed that you do not despise one of these little ones, for I say to you that in heaven their angels always see the face of My Father who is in heaven." Matthew 18:10 (NKJV)

Micaiah the prophet had a vision of heaven. 1 Kings 22:19 (NKJV), "Then Micaiah said, 'Therefore hear the word of the LORD: I saw the LORD sitting on His throne, and all the host of heaven standing by, on His right hand and on His left.'" 

The prophet Daniel had this vision: Daniel 7:9-10, "I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire. 10 A fiery stream issued and came forth from before him: thousand thousands ministered unto him, and ten thousand times ten thousand stood before him: the judgment was set, and the books were opened." Here thousands of angels are ministering to God. So, certainly angels can see God.
