What arguments does Akunna use to convince mr Brown that lesser gods act as messengers to chukwu?

Akunna argues that lesser gods serve as intermediaries between humans and Chukwu, the supreme deity, facilitating communication and supplication. He explains that these lesser gods are integral to the Igbo religious system, acting as conduits for the people's prayers and offerings to Chukwu. By highlighting the importance of these deities in traditional practices and their role in maintaining the community's spiritual well-being, Akunna seeks to persuade Mr. Brown of their significance and legitimacy within the broader context of Igbo belief.
