I don’t think I ever could be.

from Frank Ocean – Frank Ocean's Open Letter on Tumblr on Rap Genius

Meaning

God is generally held to be omnipotent (all-powerful), omniscient (all-knowing) and omnibenevolent (all-good). So perhaps Frank was referring to this conception of God when in the previous lines he spoke of never being alone. If you believe in a Deity figure like the one described above, well how could such a figure ever NOT have your back!
