. . .either by faith in this life, or by sight at the judgment seat in the next.

Hear the the words of the Prophet:

“By myself I have sworn,
       my mouth has uttered in all integrity
       a word that will not be revoked:
       Before me every knee will bow;
       by me every tongue will swear.

They will say of me, ‘In the LORD alone
       are righteousness and strength.’ ”
       All who have raged against him
       will come to him and be put to shame.”

                              – Isaiah 45:23-24

The Apostle Paul referred to the Prophet, applying the New Testament fulfillment:

“And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.  Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth.” – Phil 2:8-10
