'Heavenly Realms' in the Bible
Blessed be the God and Father of our Lord Jesus Christ, who has crowned us with every spiritual blessing in the heavenly realms in Christ;
when He displayed it in Christ by raising Him from the dead and seating Him at His own right hand in the heavenly realms,
raised us with Him from the dead, and enthroned us with Him in the heavenly realms as being in Christ Jesus,
concealed in order that the Church might now be used to display to the powers and authorities in the heavenly realms the innumerable aspects of God's wisdom.
For our struggle is not [actually] against human beings, but against rulers and authorities and leaders of this world's darkness, and against the spiritual forces of evil in the heavenly realms. [Note: "Heavenly realms" here refers to the struggle against Satanic powers which permeates life around us].
