HMMMmmm...
Then why didn't the scriptures you posted SHOW this?
[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).
of the saints - these folks are ALIVE all right; on thre EARTH!
Then the angel took the censer, filled it with burning coals from the altar, and hurled it down to the earth. There were peals of thunder, rumblings, flashes of lightning, and an earthquake. rev 8:5
When he took it, the four living creatures and the twenty-four elders fell down before the Lamb. Each of the elders held a harp and gold bowls filled with incense, which are the prayers of the holy ones. Revelation 5:8
The intercession of fellow Christianswhich is what the saints in heaven arealso clearly does not interfere with Christs 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. 2:14). Clearly, then, intercessory prayers offered by Christians on behalf of others is something “good and pleasing to God,” not something infringing on Christs role as mediator.
