Commentators agree that Jeremiah is wrestling with the age-old question of why the wicked prosper, a struggle shared by Job and the author of Psalm 73. They stress the importance of how he complains. He begins by affirming God's righteousness. This provides a model for believers: it is okay to bring our deepest frustrations and questions to God, but we should do so from a foundation of faith, not accusation, holding fast to His good character even when we can't understand His ways.
