"The people in Micah’s time carried a physical testimony of God’s love for them. But if God’s covenant with Abraham was intended to demonstrate that they were supposed to be united in love, then Micah’s reference to Jesus Christ shows how our Lord came to take away all dissensions and struggles, in order to convert the instruments of war into means of serving our neighbors [in peace] (see Micah. 4:2-3) Hence those who act as enemies, tormenting and robbing other shows their disdain peace with God. For when God reveals himself to us he does so in order to unite us along those lines of unity and concord which I have spoken. Thus when we fight among ourselves it is as if we are resisting God’s grace, as if we are chasing off the very peace that God longs to give us.

We need to consider Micah’s message “My people have risen up as an enemy” If we were truly a people of God we would be meek and kind. As St. Paul admonishes we would strive to live at peace with each other and we would do so in spite of Satan’s attempts to deprive us of such peace in this world and his constant efforts to rise up and take vengeance against each other. If we must strive at peace with all our hearts. That is why David wants us to pursue it, why he encourages us to seek it, though it steal away before us and mankind incites us to respond with evil and anger. Even then we must seek after peace. Otherwise, as Micah says, we will become as enemies, as people of war, even though we boast of being the people of God while lacking the knowledge that is required to persevere in obedience to God.
