The Man Who Stood in the Breach
Those who trust in the Man who stood in the breach should be filled with humility and gratitude which is evidenced by mercy and impartiality toward others.
And I sought for a man among them who should build up the wall and stand in the breach before me for the land, that I should not destroy it, but I found none. Therefore I have poured out my indignation upon them. I have consumed them with the fire of my wrath. I have returned their way upon their heads, declares the Lord God.
My brothers, show no partiality as you hold the faith in our Lord Jesus Christ, the Lord of glory. James 2:1
In Ezekiel’s day, invaders broke through the walls of the city. The false prophets did not risk their lives to close these breaches or to stand in them (Ezekiel 13:5). God looked, but there was no one who would do this. My study Bible notes refer to the contrast with Moses who, as a true and faithful leader, stood up in the spiritual breach for Israel when they crafted and worshiped a golden calf. Moses pleaded with God to spare Israel their just punishment and God heard him.  Now the so-called prophets ignored this need. God poured out His wrath on the nation.
Finally, God Himself took on flesh and lived among us to bring atonement for sin and mercy for His people. The Lord Jesus Christ is the Man who stood in the breach against our enemy. He is the Good Shepherd who did not flee when danger came. He bore the pain of death for us. [John 10:7-18]. James calls all who hold the faith in Him to reflect that faith in our actions and attitudes toward others. There should be no partiality based on socioeconomic classes. There should be no favoritism toward the rich nor discrimination against the poor. Those who have received mercy must be merciful or they show they deserve judgment.
Think about it
Be sure your relationships show mercy and not partiality. You have been saved by the Man who stood in the breach for us. Pride and haughtiness have no place in our lives.
