"I know the skin is a jealous skin." Parallel to "my lord" in the first verse.

"I know the sky is its competition." Consider sky for heavens of for the academic viewpoint that the Judeo-Christian god fits the paradigm of a sky god.

I'm guessing the skin is the addiction with intravenous use. The rainstorm in the first two lines of the verse may imply driving rain hitting the skin like needles - you might expect that the conditioned response for a junkie is the need for the high.

"And I need for you to be reasonable." I.e. how can I quit if the rain you pour down makes me feel the addiction and the withdrawal?
