Mankind originally sinned against God by disobediance. God told man
the punishment for the sin of disobedence was death, probably in an
effort to discourage any disobedience. But man sinned anyway and God
is still bound by His word even though He has other plans for mankind.
So God must allow man to die. But God wants an eternal relationship
with mankind and His plans seems to have been destroyed by Satan's
deception to mankind. What is God to do now?
God apparently came up with an idea to pay the price of death for man's
sin by giving His own blood by His death for man, therefore, paying the
penalty of death that man owed for his disobedience. (The life of man
depends on his blood.) Now, how is God to do this since He is eternal
and cannot die like man?
This is where Jesus, the God-man comes in. Jesus, being fully God and
fully man could die on the cross, giving up His life's blood, to pay the
price of sin that mankind owes to satisfy God's justice. Jesus proved He
was fully man by dying on the cross and proved He was fully God by
returning to life after three days and nights like He said He would and
then ascending into heaven.
Now, the living Jesus, who is still the God-man, minus the blood, can
forgive anyone that He chooses since His sacrifice of His blood is an
eternal sacrifice because He is the eternal God. He has decided to
forgive anyone that will believe and trust in Him for their salvation.
So you might look at it like someone donating blood to save your life.
