Because He is God, manifested in the flesh, or God in human capacity who was punished in our place on the cross, which is the satanic symbol for the Babylonian so called sun-god.
Why was he punished in our place and by whom?
God the Father punished Him because someone had to pay with his own blood for the sins of all mankind.
Why, and who is God the Father?
God the Father is ONE with God the Son, who is JESUS, and God the Father can't stand sin: He HATES IT!
What is sin?
Sin is disobedience to God, and the first sinners were Adam and Eve, OUR ancestors, no matter what color we have, and no matter where we live on earth, and no matter what language we speak.
Because we are their offspring, we're condemned to die and perish forever!
Now God loves us so much that He came up with a plan in order to be able to save us: He became a human Himself and He called Him His Son, JESUS (the) Christ, meaning:
'The anointed (with the Holy Spirit) 'I AM Salvation' (Christ JESUS).
'I AM (who I AM) is God's NAME.
JESUS is 'I AM' in the capacity of SAVIOR. (Or Saviour, when you're not an American).
So God loves us so much that He doesn't want to lose us and condemn us.
So someone else had to pay a very dear price: JESUS the Christ!
JESUS is God's ALTER EGO, because there is only ONE God.
Why should it be such a BLOODY and PAINFUL death, and wasn't there another option for God?
No, there was NO OTHER OPTION!
Here's the SECRET:
God created the animals FIRST, before He created the first two humans.
