"If Apostles and martyrs, whilst still in the flesh and still needing to care for themselves, can pray for others, how much more will they pray for others after they have won their crowns, their victories, their triumphs? Moses, one man, obtains God’s pardon for six hundred thousand armed men, and Stephen prays for his persecutors. When they are with Christ, will they be less powerful? Paul says that two hundred and seventy-six souls were granted to his prayers, whilst they were in a ship with him. Shall he close his lips after death, and not mutter a syllable for those who throughout the world have believed in his gospel?" (Jerome 4th century)
Sounds reasonable to me.
