Indeed we are all to pray for one another and for those who are lost. But we are not to pray to someone to guide us to the fount of Holiness which is Christ Jesus. That is the Work of the Holy Spirit not Mary or the saints. The life of Mary and other godly Christians are great examples of people walking in faith and obedience to our Lord Jesus Christ. That is why what is penned, written is Scriptures was left for us by God's Divine Grace and Love. If you can produce something God Breathed in Scriptures pointing out fellow 'call out ones' are to be prayed to please share with me.
That makes no sense. If we are to intercede for others then we should expect others to pray for our intercession as well.
