Ephesians 2:6 in the Weymouth translation says that God “….raised us with Him [Jesus] from the dead, and enthroned us with Him in the heavenly realms as being in Christ Jesus…”
God enthroned us with Jesus in the heavenly realms.
Does that sound like a Church that is defeated and is still having to battle to gain mastery over Satan?
No.God designed the Church of the Lord Jesus Christ to be triumphant, because we are sharers and partakers of Christ’s victory over Satan.
You are physically walking on earth but your spirit is enthroned with Christ at the right hand of God.
That’s your mentality in Christ.
