Christ existed eternally with His HolySpiritFather but stepped down from that glory and riches to become the sacrifice for sin. We are heirs of the Father`s glory and riches through Christ Jesus.
Don`t think that the riches are only laid up for us in heaven. Rather, take a look at the OldTestament where there was virtually no mention of heaven with emphasis on the blessings that the Lord gave to His people in the PromisedLand.
Jesus said seek first the KingdomOfGod and His righteousness and `all these things` will be added to you.
`All these things` are the blessings that this PhysicalRealm offers.
We all know there is an amazing amount of wealth in the world.
Does it make sense that that wealth should be the property of the ChildrenOfSatan rather than the ChildrenOfGod?
