Rev. 8:3 And another angel came and stood at the altar, having a golden censer; and there was given unto him much incense, that he should offer it with the prayers of all saints upon the golden altar which was before the throne.
4 And the smoke of the incense, which came with the prayers of the saints, ascended up before God out of the angel's hand.
For some the above Scriptures speaks of our prayers being the same as the time when God appeared unto Moses in the “clouds" of smoke coming from the incense” representing the prayers of the Saints.
Hebrews 12:1
Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us,
Our prayers is when through the life in the Blood of Jesus we can pass through what was the veil and into the presence of the most Holy where God may appear to us. To be quite frank it is the only thing that sustains me and I cannot even imagine life without it.
