'Realm' in the Bible

Blessed be the God and Father of our Lord Jesus, the Messiah! He has blessed us in the Messiah with every spiritual blessing in the heavenly realm,

which he brought about in the Messiah when he raised him from the dead and seated him at his right hand in the heavenly realm.

raised us up with him, and seated us with him in the heavenly realm in the Messiah Jesus,

He did this so that now, through the church, the wisdom of God in all its variety might be made known to the rulers and authorities in the heavenly realm

For our struggle is not against human opponents, but against rulers, authorities, cosmic powers in the darkness around us, and evil spiritual forces in the heavenly realm.

Indeed, this is why the gospel was proclaimed even to those who have died, so that they could be judged in their mortal flesh like all humans and live in the spiritual realm like God.
