Is the gospel good news?

If it really is why is everything so unclear when it comes to what is really going on? Where in the gospel is the running point? Jesus did not die on the cross by himselves. The law was crusified and Jesus died when the Father turn His face away from His Son. Jesus shouted "why did you abondon/forsaken me"? So what was really happened on the cross? This is the good news but never often talking about namely that sin is dead in Jesus and when I risened whith Jesus I became a perfect man and all sin washed away and can never bee in the same tempel and that is where I be and so is He and the tempel is my body. As Jesus is I am on this earth and Jesus and sin can never come together and you can not go in and out of Him. So the Bible is very clear that the very god news is that in Jesus we are His children without sin. And in Jesus I am as a new creation. The old nature can never be alive as I died when I got saved. So sin is what I was and who I am now is anything but a siner. I can't not sin as long I believe in Jesus and in the god news. Jesus said about sin, they don't believe me...
