Part of Jesus’ glory was dying on the cross.

John 20:

20 Some Greeks who had come to Jerusalem for the Passover celebration 21 paid a visit to Philip, who was from Bethsaida in Galilee. They said, “Sir, we want to meet Jesus.” 22 Philip told Andrew about it, and they went together to ask Jesus.

23 Jesus replied, “Now the time has come for the Son of Man to enter into his glory. 24 I tell you the truth, unless a kernel of wheat is planted in the soil and dies, it remains alone. But its death will produce many new kernels—a plentiful harvest of new lives. 25 Those who love their life in this world will lose it. Those who care nothing for their life in this world will keep it for eternity. 26 Anyone who wants to serve me must follow me, because my servants must be where I am. And the Father will honor anyone who serves me.
