Is Paul conflating the present with the future? We are alive now and will be seated with Christ in heaven. Or does he say this because, since there is no time with God, we are simultaneously alive in Christ on earth and seated with him in heaven? If we look back to 1:3, Paul says the Father has "blessed us in the heavenly realms with every spiritual blessing in Christ." We are blessed in the heavenly realms, we are seated in the heavenly realms.
For Reflection: If we are currently blessed and seated in the heavenly realms, what does that mean?
Let us pray. Our Father, Heavenly Father, we do praise your name. You are mighty on our behalf, raising us from death to life, from earth to heaven. You keep us close to you, sitting with you. We are blessed. We are blessed.
