In righteousness you will be established:
tyranny will be far from you;
    you will have nothing to fear.
Terror will be far removed;
    it will not come near you.
15 If anyone does attack you, it will not be my doing;
    whoever attacks you will surrender to you.

16 ‘See, it is I who created the blacksmith
    who fans the coals into flame
    and forges a weapon fit for its work.
And it is I who have created the destroyer to wreak havoc;
17     no weapon forged against you will prevail,
    and you will refute every tongue that accuses you.
This is the heritage of the servants of the Lord,
    and this is their vindication from me,’
declares the Lord.

Just a final word on Isaiah 54 before we move on. It is simply to make the observation that there is much here that will only find full and final fulfilment in the future Kingdom of God. Only then will believers be finally beautified and beyond the reach of all malevolent attack.

‘What a grand vista opens up before us in verses 11-17 – a whole renewed universe! And at its centre is the city of God, the point where heaven and earth meet and God is present with his people for ever (11-17). This city is the final resting place of the servants of the LORD, the reward and vindication for all that they have suffered because of their faithfulness to God (17).’ Barry Webb: ‘Isaiah’, p.216.

‘In verses 11-12, Isaiah gives a figurative description of Jerusalem following the exile. But it is even more a description of the new Jerusalem, which will come down from heaven at the end of history; this heavenly Jerusalem will be prepared as a bride beautifully dressed for her husband, the Lord Himself (Revelation 21:2,10-11, 18-21).’ Tom Hale: ‘Applied Old Testament Commentary’, p.1058.
