Isaiah 45:25

In the Lord -It shall be only in Yahweh that they shall find justification, and this must mean, that it is by his mercy and grace. The entire passage here, I suppose, has reference to the times of the Redeemer (see the notes atIsaiah 45:21-24). If so, it means that justification can be obtained only by the mercy of God through a Redeemer. The great truth is, therefore, here brought into view, which constitutes the sum of the New Testament, that people are not justified by their own works, but by the mercy and grace of God. All the seed of Israel -All the spiritual seed or descendants of Jacob.
