“In all their affliction he was afflicted, and the angel of his presence saved them; in his love and in his pity he redeemed them; he lifted them up and carried them all the days of old” (v9). Isaiah reminded Israel that God had proven Himself to be their Savior (v8). He led them out of Egypt under Moses’ leadership, He provided for them in the desert, and He fought against their enemies. Even though they “rebelled and grieved his Holy Spirit,” (v10) earning His anger, He continued to be their Father and Redeemer (v16).
The same God who rescued Israel over and over sent Jesus to save us once and for all. His love and mercy don’t run out.
