No Contradiction Indeed, Jesus is the Son of Man spoken of in Daniel 7:13-14. Jesus self-described Himself with this phrase over 80 times during His ministry in the first century. (Examples: Matthew 12:32, 40, Luke 12:40, et al.)
And Jesus did receive a Kingdom with dominion and glory...which is an everlasting Kingdom. Jesus declared as such in His final speech to the disciples (Matthew 28:18). This Messianic Kingdom in Daniel 7 is the same one prophesied in chapter 2. Both were to be established during the Roman Empire age. (See Matthew 4:17, Repent, for the Kingdom of Heaven is at hand (near). But note Paul's definition of the Kingdom: righteousness, peace, and joy in the Holy Ghost.)
In fact, the expectation of this fifth Kingdom was so rife among the Jews in the first century, that the ancient Roman historians, Seutonius and Tacitus, wrote about it. Of course they mocked the idea that a lowly Judaean nation could ever supplant the mighty Roman Empire, and set up another Kingdom!
The Saints' Kingdom? But what about the saints obtaining this Messianic Kingdom? The answer is recorded in the New Testament, and comes from the mouth of the Messiah Himself:
I (Jesus) confer on you a kingdom, just as Mt Father conferred one on me...so that you may...sit on thrones, judging the 12 tribes of Israel. (Luke 22:29)
Do not be afraid, little flock, for the Father has been pleased to give you the Kingdom. (Luke 12:32)
Notice that this did not mean that the "saints" supplanted Jesus or took over His Kingdom, leaving Jesus as a "King without a kingdom". The Apostles gave us insight and understanding about this in their epistles:
God raised us up with Christ and seated us with Him in the heavenly realms in Christ Jesus...(Ephesians 2:6)
Giving thanks to the Father who has qualified you to share in the inheritance of the saints in the kingdom of Light, for He has...brought un into the Kingdom of the Son He loves...(Colossians 1:12)
To Him...who has made us to be a kingdom and priests to serve His God and Father...(Revelation 1:6; 5:210, 12:10)
Jesus has indeed been given a majestic Kingdom (ala Davidic throne). And he has been given the power to delegate saints to be His ambassadors in this kingdom...as well as priests to intercede for the nations...as well as judging. Verse 27 of Daniel is fulfilled to the letter, by all the amazing events of the Messiah's ministry in the first century, as well as the beneficent gifting of God.
