I understand your position a little bit better, I think, but 1Corinthians 15 gives me pause in seeing that the last trump has occurred, where the last enemy that shall be destroyed is death (1Cor15:26), and death and Hades are thrown into the lake of fire (Rev 20:14). Now, if the false prophet and the antichrist have been cast into the lof, then they are gone forever and no one will see nor hear from them ever again, but we still see and hear of death all too frequently for it to have been destroyed. Will it continue to exist perpetually 'in this world'?
Sure. I have explained this earlier but I'll try again.
Who holds the keys to death and hell now? Revelation 1:18 Jesus says He does. Who had them before the resurrection?
So why aren't are there still some of the effects of sin and death still with us?
Let's look for a moment at how death began. God made Adam and Eve. He placed them in the garden with 1 rule, and told them that in the day they broke that rule they would surely die. They did break the rule, and they did both begin to die physically, and immediately they died spiritually. But Adam still lived beyond 900 years. As more people come into the world, sin increases and longevity decreases. By the time David comes into the world, life expectancy is 70 to 80 years...Psalm 90:10. During the first century it was still lower. Today it is in the 70's again.
Another line of thought...
In the beginning, God came and walked each day with Adam and Eve and spoke with them. After sin, God spoke sporadically to some in the OT. Then He began speaking through prophets. And eventually 400 years of silence until the advent of Christ.
Look at the layout of the temple. It had an outer court for Gentiles. Inside this was a court for Jewish women. Inside this was a court for Jewish men. Inside this is a court for the priests. And within this was the Holy of Holies where 1 man 1 time each year was allowed to go in and speak with God.
From the onset of sin to the advent of Christ, things were getting worse both physically and spiritually. People were dying progressively faster and God Himself was increasingly difficult for people to draw near.
Then Jesus comes. He dies and is resurrected. The veil is rent. He shows up with the keys to death and hell after announcing that He would build His church and the gates of hell would not prevail against it. Far from being hard to reach, all believers have been made priests and have direct access to the throne room of God. There's a new Sheriff in town.
But just as things didn't deteriorate over night, God has chosen to put things back as they were in very deliberate fashion. But make no mistake. Jesus came to destroy the works of the devil. And He is, and He will continue to do so. The effects of sin will eventually be reversed, and the kingdoms of this world will fully become the kingdoms of our God and Christ...Revelation 11:15.
The effects of sin weren't immediately known but increased over time. Why is it odd that the effects of the resurrection would do so as well?
