The 1000 years of Rev. 20 is comparable to the 40 years of Israel wandering in the wilderness in the Old Testament. The 40 years were physical, but the 1000 years are symbolic.
The angel of Rev. 20 is holding a great chain in his had in order to bind Satan.
Rev. 20:6 – The first person resurrected to never die again was Jesus. We have a part in that resurrection when we are raised from the grave of sin to never die again spiritually.
We avoid the second death by following the pattern given by God. Use with Rev. 20:6.
