Hi Jaguar,
People like Joe Mizzi needs bible verses. So, I hope these help…
St Paul tells us that prayers should be offered for all people (1 Tim 2:1). He even asks that we pray for him (eg, Ro 15:31, Eph 6:19, Col 4:3). If fact, the practice of asking others to pray for us is highly recommended in Scripture, probably because we are God’s family (1 Co 12:27), and family protect and help each other (1 Co 12:26). God’s family is not restricted to those living on earth, but also to those who die (Ro 14:8, Lk 20:38).
God has forbidden us to try and communicate with the dead for information as the pagans did in the ancient lands of Israel (Dt 18:10-11). Such practices would today be known as a seance. But if all communication with the dead is evil, then that would mean Jesus did something evil during the Transfiguration, when Peter, James, and John witnessed Elijah and Moses talking with Jesus (Mt 17:3 and Mk 9:4). How beautiful it would be to speak with somebody who is so close to God (1 Co 12:24).
In the book of The Revelation, we learn that the saints offer prayers to God (Rev 5:8), and that they are aware of events on earth (Rev 6:9). So, let’s pray and ask for their help. Afterall, the prayers of a good person has a powerful effect (Jam 5:16).
