Although the Supreme Personality of Godhead constantly watches the activities of the world, no one sees Him. However, one should not think that because no one sees Him, He does not see, for His power to see is never diminished. Therefore, everyone should worship the Supersoul, who always stays with the individual soul as a friend.
Srimad Bhagavata Purana

यं न पश्यतिपश्यन्तं चक्षुर्यस्य न रिष्यति । तं भूतनिलयं देवं सुपर्णमुपधावत
yaṃ na paśyatipaśyantaṃ cakṣuryasya na riṣyati | taṃ bhūtanilayaṃ devaṃ suparṇamupadhāvata
