One of the promises to believers is that we will rule and reign with Him. That can only take place in reading the Revelation and seeing the fulfillment during the Millennium.
I am amazed at how often folks will argue over the validity of and rendering of certain passages, yet when it comes to this passage they arrange some scheme to discredit the statements by removing their veracity.
The church is already ruling with Him. We see that God has always had a council in the OT, per Job. Paul says we (physically) sit with Christ since the Cross in Paradise. Not sure why any one would not accept that as physical already. There has been a ongoing physical resurrection since the Cross. If that is Phariseesism, then so be it.
David pointed out that He could not sit at that time. He was waiting for the redemption of the Cross. Jesus explained the OT believers were waiting in Abraham's bosom, but Paul claimed that changed with the Cross. Jesus told the thief that on the Cross. Paradise was physically opened in heaven for the church that day. The OT believers from Abraham's bosom were the firstfruits. That is the first resurrection per Paul.
"But every man in his own order: Christ the firstfruits (Abraham's bosom and ongoing arrivals into Paradise); afterward they that are Christ's at his coming (only those alive and remain). Then cometh the end (those alive on earth at the end of the Millennium), when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power."
The OT waited in Abraham's bosom. The church is ongoing, complete at the Second Coming. But the kingdom completion comes at the end of the Millennium, 1000 years after the Second Coming.
That would only be confirmed in hindsight after 1991 years of church history.
