Matthew 25:32-33

All the nations will be gathered before Him (for judgement); and He will separate them from one another, as a shepherd separates his sheep from the goats; and He will put the sheep on His right (the place of honor) and the goats on His left (the place of rejection).

As Christians we know judgement is coming. There are others who do not know the Lord or the hope of Salvation. Why we are still here on this earth we can pray for the lost and reach out to those we know who are not saved. We can be kind and not act like the world. We can show love when others hate as we represent Jesus here on earth.
