Kings + priests in Christ shall rule and reign with Him on the earth

And have made us kings and priests to our God;
and we shall reign on the earth.
Revelation 5.10 

“a royal priesthood”

But you are a chosen people, a royal priesthood,
a holy nation, God’s special possession
1 Peter 2.9

Kings reign over land
Priests reign over the temple of God (the body)

Kings + priests should glorify God in their body and spirit
Their “body is the temple of the Holy Spirit” who is in them

Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? 20 For you were bought at a price; therefore glorify God in your body and in your spirit, which are God’s.
1 Corinthians 6.19
