Revelation 14 falls into three sections, and it opens with the Lamb standing on Mount Zion with his people. Read beside Psalm 2, 14:1 shows that the church dwells in heaven now. The law of the Lamb is to give your life away.
Nationalist causes have bent Psalm 2:8-9 to their own ends, and that is abuse. Christ will rule the nations with a rod of iron at his second coming. For now he rules as the child of 12:5, and his rule runs through the cross.
The woman’s child in 12:2 is Christ, the single promised seed of Abraham (Galatians 3:16). God hides the elect in him. Psalm 2 promises him the nations, and Matthew 18:3 shows that he rules now as a child.
