Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him in love. He predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace, with which he has blessed us in the Beloved. In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known [3] to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.

Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places

In this first statement, Paul identifies God as he has been revealed in the Gospel (Father and Son) and praises this God for raising Christ from the dead and bringing him up to the Heavens to rule at His right hand.  It is Jesus who was raised by the Spirit and Jesus who is seated in the heavens.  But in blessing Jesus God also blessed those who belong to Jesus.
