'Before God' in the Bible

Then I saw seven trumpets being given to the seven angels who stand before God.

and the smoke of the incense with the prayers of all the saints rose up from the angel's hand before God.

Then the sixth angel blew; and I heard a voice from the four horns of the golden altar before God,

Then the four and twenty Presbyters who are seated on their thrones before God, fell on their faces and worshipped God,

Then I heard a loud voice in heaven saying, "Now it has come, the salvation and power, the reign of our God and the authority of his Christ! ??for the Accuser of our brothers is thrown down, who accused them before God day and night.
