God shows no partiality. He even bestows blessings on non-Christians.
By becoming Christians though, we are made joint heirs of the kingdom alongside Christ. After the judgement, Christ will give back the authority he was given as king to our father.
We have inherited this kingdom with Christ. We reign in this kingdom right now.
1 Peter 2
9 But you are a chosen generation, a royal priesthood, a holy nation, His own special people, that you may proclaim the praises of Him who called you out of darkness into His marvelous light;
Revelation 1
To Him who loved us and washed us from our sins in His own blood, 6 and has made us kings and priests to His God and Father, to Him be glory and dominion forever and ever. Amen.
What is your reference to blessings about? I mean....it sounds like you're thinking that there are blessings associated being in Christ, and of course there are spiritual blessings, but were you thinking something more than that?
