Humans were created to be an interface between heaven and earth. We have a purpose and it's not all about us. Unfortunately, Adam's sin in the Garden broke our connections to both heaven and earth. Now we fight daily with both just to survive.

Coincidentally, the horns on the bronze altar of the Tabernacle are material metaphors for power, authority, and connection to heaven. In some sense that we will probably never fully comprehend, they were functional, not merely decorative. The blood of the sin offering is placed on the horns (heaven) and base (earth) of the altar, temporarily fixing our connection to both.

(Pagan altars in Canaan also featured horns on the corners. Understand from this that something isn't sinful or pagan just because pagans do it.)
