I do believe our senses is limited.
Well yeah, we know that. We only see a small portion of light, hear a small portion of sound, etc. But... we also know we can invent Chandra and Hubble to see beyond our eyes (and not by faith, but by science and technology - and in the case of Hubble, like lots of science, by trial and error.)
Still, all of that give no reason why a non-material world exists beyond the material, that is faith. And just because physics can not explain all at the present time, is no reason to leap into metaphysics.
And no matter what limits our senses have, our grammar is very exact. It's senses (plural) ARE limited, not is, which is singular.
