How about a Bible verse that says everything to believe is in the Bible and never go outside the Bible for anything ???

But asking one person to pray for you in no way violates Christ’s mediatorship, as can be seen from considering the way in which Christ is a mediator. First, Christ is a unique mediator between man and God because he is the only person who is both God and man. He is the only bridge between the two, the only God-man. But that role as mediator is not compromised in the least by the fact that others intercede for us. Furthermore, Christ is a unique mediator between God and man because he is the Mediator of the New Covenant (Heb. 9:15, 12:24), just as Moses was the mediator (Greek mesitas) of the Old Covenant (Gal. 3:19–20).
The intercession of fellow Christians—which is what the saints in heaven are—also clearly does not interfere with Christ’s unique mediatorship because in the four verses immediately preceding 1 Timothy 2:5, Paul says that Christians should interceed: “First of all, then, I urge that supplications, prayers, intercessions, and thanksgivings be made for all men, for kings and all who are in high positions, that we may lead a quiet and peaceable life, godly and respectful in every way. This is good, and pleasing to God our Savior, who desires all men to be saved and to come to the knowledge of the truth” (1 Tim. 2:1–4). Clearly, then, intercessory prayers offered by Christians on behalf of others is something “good and pleasing to God,” not something infringing on Christ’s role as mediator…
Not only do those in heaven pray with us, they also pray for us. In the book of Revelation, we read: “[An] angel came and stood at the altar [in heaven] with a golden censer; and he was given much incense to mingle with the prayers of all the saints upon the golden altar before the throne; and the smoke of the incense rose with the prayers of the saints from the hand of the angel before God” (Rev. 8:3-4).
If you hold onto the oral tradtion St Paul commands you to and realise that Church is the pillar and foundation of truth, then you will know that praying to God through the Saints is perfectly fine.
Under your protection we flee, O Holy Mother of God; despise not our petitions…
This is one of the oldest known Marian prayers and was found (in A.D. 1917) on a Christian Egyptian papyrus dating to the 200s. This prayer has been prayed for millennia as a concluding prayer in Compline.
“[Appealing to the three companions of Daniel] Think of me, I beseech you, so that I may achieve with you the same fate of martyrdom.” Hippolytus of Rome, On Daniel, 11:30 (A.D. 204).
“Only may that power come upon us which strengthens weakness, through the prayers of him* who made his own strength perfect in bodily weakness.” Gregory of Nyssa, Against Eunomius, 1:1(A.D. 380).
“Furthermore, as to mentioning the names of the dead, how is there anything very useful in that? What is more timely or more excellent than that those who are still here should believe that
the departed do live, and that they have not retreated into nothingness,* but that they exist and are alive with the Master…
Useful too is the prayer fashioned on their behalf…For we make commemoration of the just and of sinners: of sinners, begging God’s mercy for them; of the just and the Fathers and Patriarchs and Prophets and Apostles and Evangelists and martyrs and confessors, and of bishops and solitaries, and of the whole list of them…” Epiphanius, Panarion, 75:8 (A.D. 377).
“But God forbid that any in this fair assembly should appear there suffering such things! but by the prayers of the holy fathers, correcting all our offences, and having shown forth the abundant fruit of virtue, may we depart hence with much confidence.” John Chrysostom, On Statues, Homily 6:19 (A.D. 387).
I was asked for chapter and verse to prove my point and I courteously complied. I then asked you to do the same to prove your point. Now you are making excuses why you can’t find it. Where in the bible does it say there is another mediator in heaven we should pray to?
