Regardless the debate on eschatology, we know that through faith in Him, He provides for all things.
Even amongst scholars, a good grasp of eschatology only comes after a good foundation in the other doctrines in Scripture. That is one reason why eschatology comes in the rear chapters of most rigorous systematic theologies.
Psalms 2, 110, Daniel 7, and Ephesians 4 and Hebrews 1 provide significant guidance regarding the Session of the Son of God and when the seals are broken after which He sits on the throne of David forevermore.
Pretrib, premil believers tend to interpret those passages literally, while preterists tend to spiritualize the Kingdom of God and Kingdom of heaven. Pretrib, premil recognizes there are things happening today in preparation for Him opening those seals and although having an inheritance, has not yet been placed on the throne.
By remaining in fellowship with God through faith in Christ, He continues to grow us through faith in Him to be prepared to receive the crowns He has predestined for us.
