It is currently debated amongst scholars whether the sources were added to the Cross out of reverence for Viking beliefs and still clinging to their own identity or as a way to parallel Norse mythology (ie Ragnarok, the death of Baldr) with Christian beliefs (ie the Apocalypse, the crucifixion of Christ). Among the parallels is Loki being bound is allegorical for Satan being bound, the death of Baldr accompanied by Hod and Nanna interchangeable with Christ's death as witnessed by Longinius and Mary Magdalene, and the battle Odin has with Surtr similar to how Christ ultimately conquers the Devil.
