It is normal that wherever people gather together, relational challenges develop. Consider the situation of Moses in the desert with thousands of people to feed and to rule. Without the extraordinary help of God, such a people would never succeed in living in peace.
Yet, the Lord simply came down in a cloud and took some of the Spirit He had given to Moses and bestowed it upon 72 others.
In today's passage from Isaiah, we see that God's word, spoken to the Israelites of His time, speaks powerfully to us today. As a nation we are dealing with issues very similar to the issues that Isaiah addressed in his time.
Isaiah's encouraging words follow a series of oracles spoken against Israel's enemies, but especially against Edom, that desert kingdom that took advantage of Israel's own diminished faith and its captivity in Babylon.
