A question for Christians about another deity.

Odin Sacrifices Himself To Himself To Gain Knowledge Of Runes

Odin is attributed with discovering the runes. In a sacrifice to himself, the highest of the gods, he was hanged from the world tree Yggdrasil for nine days and nights, pierced by his own spear, in order to learn the wisdom that would give him power in the nine worlds. Nine is a significant number in Norse magical practice (there were, for example, nine realms of existence), thereby learning nine (later 18) magical songs and 18 magical runes.

Do you believe this? After all, runes really exist.

Runes

Runes (Proto-Norse: ᚱᚢᚾᛟ (runo), Old Norse: rún) are the letters in a set of related alphabets known as runic alphabets, which were used to write various Germanic languages before the adoption of the Latin alphabet and for specialised purposes thereafter. The Scandinavian variants are also known as futhark or fuþark (derived from their first six letters of the alphabet: F, U, Þ, A, R, and K); the Anglo-Saxon variant is futhorc or fuþorc (due to sound changes undergone in Old English by the same six letters).
