The plot is thin, the story is tripe, and it simply still does not make any sense.
It doesn't make sense because you have not read enough theology.
Let me try to explain to you how I see the story.
1) God is all powerful and all knowing.
2) He decides to create the Universe to glorify himself and share his immeasurable love and goodness with creatures smart enough to recognize this gift.
3) He gives free will to his creations because it helps glorify God. With free will, man can recognize that God is good and willingly follow him. That contributes to the glory of God.
3.1) What I mean by free will is the choice of each man to follow God or not lies with the man and not with God.
4) Because it is His will that his creation gets free will, problems will occur. The chief culprit, Satan, exercised his free will to oppose God and in the process, also corrupted man.
5) God cannot tolerate sin. Therefore man cannot be with God anymore.
6) Which means that man automatically goes to Hell when he dies.
7) But God love man so much he himself took the punishment for man's sins.
7.1) This punishment is required because God is perfect and His perfect Justice requires punishment for sins.
8) Any man who accept Jesus Christ's gift is in the eye of God forgiven and sin free. Man's debt to God has been paid in full.
9) Sin free people get to live with God, whose dwelling place is called Heaven.
