Dead men don't pray.
Except, he is alive. The dead, or the faithful departed, are saints because their time on earth is over. They are the ones who have completed the race, kept the faith, and have been given the crown of righteousness (2 Timothy 4:7,8). When they stood before the Son of Man, they were judged to be righteous and told, Come, you who are blessed by my Father. Inherit the kingdom prepared for you from the foundation of the world (Matthew 25:34). They are the sheep for whom the Good Shepherd freely laid down his life (John 10:1-18); the ones who have been escorted by Jesus to the Fathers house (John 14:1-3); and the great multitude which no one can count that are gathered around Gods throne (Revelation 7:9).
Revelation 5:8
His soul is alive, sees all and can pray for all. (Even though his body is dead.)
You do believe that a human has a body AND a soul, don’t you?
Pope John Paul II was “perhaps the most influential voice for morality and peace in the world during the last 100 years”.
