Jesus lives eternally as a Supreme Priest to plead with God for us.

Hebrews 7:20-25

20 Furthermore, when God appointed Christ, it was when God solemnly declared that Christ would be a priest [LIT]. When God appointed former priests, it was not by his solemnly declaring that they would be priests. 21 However, when he appointed Christ to be a priest, it was by these words that the Psalmist wrote in Scripture:

The Lord has solemnly declared to the Messiah,

—and he will not change his mind—

“You will be a priest forever!”

22 Because of that, Jesus guarantees that the new covenant will be better than the old one.

23 And formerly, the priests could not keep serving as priests, because they all died [PRS]. So there were many priests to take the place of the ones who died. 24 But because Jesus lives eternally, he will continue to be a Supreme Priest forever. 25 So, he can completely and eternally save those who come to God by trusting in what Jesus has done for them, since he lives forever to plead with God to help them.
