Adam Clarke on Isaiah 62:12

They shall call them - These characteristics seem to be put in their inverted order. -

1. God will not forsake them.

2. They shall be sought out.

3. They shall be redeemed. And,

4. Be in consequence a holy people.

1. When God calls, it is a proof that he has not forsaken.

2. When he seeks, it is a proof he is waiting to be gracious.

3. When the atonement is exhibited, all things are then ready.

4. And when that is received, holiness of heart and life is then to be kept continually in view, as this is the genuine work of God's Spirit; and without holiness none shall see the Lord.
