His birth brought joy to the world. His death gave us life and more abundantly. His birth brought his personal presence to mostly the lost sheep of the house of Isreal. His death brought the presence and power of the Comforter, the Holy Spirit to every child of God, Jews and Gentiles alike. If He had lived forever in flesh, we would have died forever on the other side of eternity, seperated from God, having never had remission of sins.

He gave his life for us that we might live. His death reconciled us to God, breaking down the middle wall of partition.

Through his birth and presence, he blessed, healed and delivered the people then present. Through his death and even in his physical absence but spiritual presence, men, past and also this present time, are still being healed by his stripes, blessed with all spiritual blessings, delivered from the powers of darkness, and more importantly being saved by His grace, (harvested unto life eternal), through faith in his name, after the finished work of redemption. Glory to God.

The two is very very important. For without birth, there is no death and without death, birth will be meaningless.

His death

Both. Everything about Christ is OUTSTANDING. He lived and existed before the foundation of the earth. His birth earned us hope and His death earned us victory. He lives on. He is not dead. JESUS CHRIST IS ALIVE TODAY. Halleluyah

One must come before the other,they re all important. But his resurrection is the confirmation of the first two events. Had it not happend,the first two events would have been meaningless.
