The two phrases that assert Paine's belief that the humans' deaths of the colonists' in the armed fightback against the British colonizers was worth the result it laid are mentioned beneath this statement:
1. "Let it be told to the future world, that in the depth of winter when nothing but hope and virtue could survive, that the city and the country, alarmed at one common danger, came forth to meet and to repulse it"
2. "Say not that thousands are gone, turn out your tens of thousands;"
These two are the best possible answers in my opinion. To support my assertion I would like to elaborate my understanding to you.
So, the first phrase by T.Paine wants to outshine the losses of the present by connecting the rebellious moments with the future. He wants that the echo of these sacrifices should be heard in later years as it was worth happening. Moreover, the second phrase showcases valiance of the martyrs who were not afraid of the armed fight and chose liberty. This again shows writers assertion that the colonists' struggle was worth the result.
