Why did Jesus have to come to earth to die for mankind and why was he the perfect sacrifice for the sin of mankind? 

Why did the restoration of man have to involve the shedding of blood?

 God made man in his image and gave him authority over creation to reflect his righteous rule while being connected to him as their source. 

Just the way a fish cannot do without water and a tree cannot do without the earth, Man was created to be connected to God as his source, sustainer and shield.

Death is when the Spirit of God is disconnected from the spirit of man and man is isolated from God.

The Good News is that the dominion of the kingdom of God now resides in humans through the Spirit of God within.

Philippians 3:10
