Immutability:

Hebrews 6:17-18

In the same way God, desiring even more to show to the heirs of the promise the unchangeableness of His purpose, interposed with an oath, so that by two unchangeable things in which it is impossible for God to lie, we who have taken refuge would have strong encouragement to take hold of the hope set before us.

Hebrews 13:8

Jesus Christ is the same yesterday, today and forever.
