Pray against polygamy, both among the older people and this new generation, who are following the steps of their ancestors and ending up in premature marriages.
Pray for the grandmothers and wise women who are responsible for the premature marriages in continuation of the traditions of the ancestors.
Pray for the few true Christians who battle against these cultural practices and find the pressure against them and their families huge.
Pray that God would raise up healthy churches, true churches without these cultural practices  mixed in and churches committed to the Word of God.
