Ok, so this is a massive point you present, i can straight away tell you i cannot do it justice but i will try.
You need to go to the start of the story to get the full picture. God is love, and love is God therefore everything that comes from God can only be out of love. This is the basic Christian belief. Next, God always existed..God is The creator...The father...this is how we humans with our human brains can understand him. God created the angels, satan was an archangel. The top angel. He thought he could be God and in doing that, created darkness. Because he fell/tore apart/chose the opposite from God (who is love). Now satan wanted to be God and thinks he is God in his ignorance and pride. He goes on now through all history believing that and deceiving the whole world. The first deception however, and key point, was in the garden of eden when man disobeyed God, ate the apple and fell from God's grace (Man lived in 'heaven' in unity with God and one another in God) as a result of man eating the forbidden apple. So mans now been wandering around the earth since then screwing it up every which way. God's still there, he's always had a path in place for us to get back to him. Only some really try and are chosen.
Now the path we have now (as apposed to old testament), is God coming among us in human form, in Jesus Christ to show us the way. 'For God so loved man that he sent his only Son to die for our sins'. You need to think about it like this...God is love, only love, he created us with free will...if he didn't then he wouldn't be perfect love because he would be forcing us to love him. We chose our fate back then, and everyday we re-choose our fate again, because he will take us back when ever we truly want to go back. (this means choosing absolute love and goodness in the name of Absolute Goodness, 'The Father The Son and The Holy Spirit', God.
So Jesus is God, thats why he was sacrificed. It was God's sacrifice for man. For man's sin. We don't walk through this world having no consequence on it. Sin is real, it separates us from God. That separation is the pain and fear we feel that tortures us, that we constantly try to run away from and mask with other things. Thats the darkness were living in that we feel.
There are people that God has gifted with many things. The ability to not eat food, not sleep, heal and all sorts of other gifts in the spiritual realm. These people can be found in the Orthodox Christian faith. This is the church of Jesus Christ, meaning it started at 33 A.D when Jesus resurrected after being sacrificed. The Catholic church split from the Orthodox in 1054AD. In 1517AD started the protestant reformation, which split from Catholicism (all these other little churches and cults claiming Jesus as there Saviour stem from Protestantism). This is where the watered down flimsy 'evolved being' kind of shallow rooted stuff has been able to grow.
I'm talking a little bit of history so that you understand there is a clear cut path to God. Its your choice to seek it out and learn from it or not. Just like all truth, you won't read about it, or see it in the paper or have Julia Roberts find it in India watching one of your favourite movies. Your free will. This time we have now, in our lives, is to make choices. These choices shape our soul, whether thats a soul of light or darkness. We have God available to us while we live here, but that means changing who we are, to be ultimate goodness as God is.
Anyhow, the sacrifice stuff was on our level back then. We don't need to worry about that until we have an understanding of the new testament.
Let me know anything and everything i missed
