Please note: All of the people Paul asked to pray for him were ALIVE. They were living and breathing, just like your neighbor or friend. They were not dead. Yes, asking a friend or relative to pray for you is perfectly ok, in fact we are taught to do it. Show me one instance in the Bible where anyone was taught to pray to those who are already dead.
Matthew 22:31-32.
"Please note: All of the people Paul asked to pray for him were ALIVE."
Read the beautiful ending of Romans Chapter 8. Death will NOT separate us from God's love. Because our physical bodies have died doesn't follow that we are dead. God is the God of the Living, as God Himself says in Scripture.
Where does the Bible say that death separates us from the Body of Christ???
