The kingdom of God and the kingdom of heaven are not the same thing.
The kingdom of God is a spiritual kingdom, namely the church. That kingdom is in effect now.
But there will be a future kingdom of heaven where Christ reigns physically on earth, which will be fulfilled during the millennium after the Tribulation.
OT prophecy focuses on this millennial reign and overlooks the church age, because the church age is coincident with the times of the gentiles.
Regarding the antichrist deceiving people during the millennium, this is impossible as he will be in the lake of fire and Satan will be bound after the Tribulation. Revelations indicates that the millennium is after the Tribulation, so these two players will be out of commission. Satan is only briefly released toward the end of this period, and the Antichrist is not released from the lake of fire at all.
