Now we get to a term the dispensation of the fullness of times. This I would conclude to be Revelation 14 & 20 when Christ reigns for 1000 years, and all the redeemed will be with Him.

We have a seal which is the Holy Spirit. That is God’s seal that we are His possession. Paul calls this our earnest or our guarantee. We get to keep Him in us until we finally get to Heaven. At the age of 81 I have been with God for 60 years and I have never lost God’s presence because of the Holy Spirit.
