This is basically the same when we pray to the Saints/Mama Mary to help us pray to Jesus. Saints are the heroes of our faith if we will look at their lives we will see Jesus on them. They lived their lives emulating the virtues of Jesus.
Why do we ask the saints our relatives and friends to pray for us? The answer rest on the importance of common prayer with others. Jesus said: “For where two or three are gathered together in my name I am there present in their midst.” (Matthew 18:20) Sometimes we even ask our relatives who’s already in the next life to pray for us because we believed that they are already in heaven.
In his letter (to the Colossians 4:2-3) Saint Paul said: “Persevere in prayer, being watchful in it with thanksgiving; at the same time, pray for us, too, that God may open a door to us.”
We can pray directly to God, it’s actually upon us if we want to ask the help of the Saints to pray for us, if we want to ask our relatives and friends to pray for us. The freedom of choice is ours to take.
