I am revising my question and ask again:
Isaiah 65:17 and 66:22 say that new heavens and new earth will be created or made, but Psalm 148:5-6 say that the present heavens and earth will exist forever. Especially, the verbs in the 2 verses in Psalm 148 are about completed action (i.e. the present heavens and earth are already completed and will never vanish). How can the former 2 verses reconcile with the latter 2 verse? Thank you for your help.
