Ask that God will help them each take the time for prayer and study in the Bible (very important) so that God's truth is illuminated to em and doesn't come off as dry, dead, fruitless, or even seem mundane. God's Spirit can easily handle that.
Ask that God will continue to use them to plant, water and harvest seeds of truth from Him - you know how people still need Jesus far more than religion, local churches, and man's organizations. Ask in faith that they will enjoy God's mighty power daily, His holy passion inside, and abundant provision for the work.. no matter the circumstances they are facing.
Ask that they will hear from the Lord and have some spiritual backbone to keep living and telling the truth regardless of the opposition and outcome.
