Yes, these things have already happened, however they have happened many times.
In each of the 7 seal/ages there are 7 Seasons, six seasons of for labor and one the last season is for Rest.
In each of the 6 seasons of labor all generation must die, but they are "born again" into a new body. The last season, the 7th season is for Rest, which means that all in that seal must die except two (2).
In the 7th seal/age "All Time" (A Time, Times, and Half-a-Time) comes to an end, therefore in the 7th season of the 7th seal all living things on the earth are given Rest (no flesh shall be spared).
It is NOT that it will happen tomorrow, it is when it happens to YOU. Will you be willing to give up everthing for Jesus' SAKE, for His words.
Relevent Scripture: (understand) Luke 4:5-7 and Matt 4:8-9 these tell of who it is that has the authority to give riches/wealth/fame/power on earth, an Job 1:12 tells who gave the devil (Satan) this authority.
The Lord (God the Father) said onto my Lord (LORD God, the Christ, Jesus) sit here on my right until I make your enemies your footstool.
