Micah must have felt quite lonely as he faced the proud, powerful people of Jerusalem. Like Elijah (1 Kings 19:10), he probably felt as if he were the last faithful believer on the planet (Mic. 7:2). Wherever he turned he seemed to find people who were blood-thirsty, corrupted, treacherous, and deceitful. Even the members of his own family were not to be trusted (7:2-6).
Faced with such a world, Micah found reassurance in the fact that God remains in control and takes care of His faithful children, no matter what others may be up to (7:7). This truth can be a great hope for believers today, especially when we find ourselves in the minority, or even all alone among people who do not know or honor the Lord.
