The first 2 chapters in the Bible tell us how we got here.
The 3rd chapter tells us about how man screwed up and sinned against God.
The Rest of the Bible, except for a few things in Revelation is God trying to fix what man screwed up.
When God created man life was easy. There were no droughts, floods or natural disasters of any kind. Food grew out of the ground at ease. No one got sick and no one would ever die. As a matter of fact no animals or plant life would ever die either.
So because of our sin, death was brought upon the human race. Now we will all die. So God had a plan to fix death. His plan was to send Christ (God incarnate) into the world to live a sinless life and to die on the cross for the sins of mankind. So now those of us who put our faith in that fact are no longer held under the penalty of sin.
Romans 5:10-11 For if while we were enemies, we were reconciled to God through the death of His Son, much more, having been reconciled we shall be saved by His life. "And not only this, but we also exult in God through our Lord Jesus Christ, through whom we have now received the reconciliation.
P.S. Romans chapter 5 might be something worth reading before bed time tonight?
