The increase of his gouernement and peace shall haue none end: he shall sit vpon the throne of Dauid, and vpon his kingdome, to order it, and to stablish it with iudgement and with iustice, from hencefoorth, euen for euer: the zeale of the Lord of hostes will performe this.
Isaiah 9:5 Surely euery battell of the warriour is with noyse, and with tumbling of garments in blood: but this shall be with burning and deuouring of fire.

Isaiah 9:7 The increase of his gouernement and peace shall haue none end: he shall sit vpon the throne of Dauid, and vpon his kingdome, to order it, and to stablish it with iudgement and with iustice, from hencefoorth, euen for euer: the zeale of the Lord of hostes will performe this.
Isaiah 9:8 The Lord hath sent a worde into Iaakob, and it hath lighted vpon Israel.
Isaiah 9:9 And all the people shall knowe, euen Ephraim, and the inhabitant of Samaria, that say in the pride and presumption of the heart,
The verse centers on "increase", "gouernement", "peace", "shall", "haue", "none", and "vpon". It is saying that the verse draws attention to "increase" and "gouernement", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "For vnto vs a childe is borne..." into verse 8's "The Lord hath sent a worde into...", so "increase" and "gouernement" belong inside that flow. In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "increase" and "gouernement" with trust shaped by these words, not by a vague optimism outside the passage.
