For those who might have never heard th gospel, I'll brake it down for you from the beginning. God created the first people, Adam and Eve. Back then the earth was paridice. There was no hurt, pain, work, or stress. God actually physically kicked it with Adam and Eve. It was heaven on earth. When they sinned, they could no longer fellowship with God because God and sin can't be together. That is why their is bad things that happen today. People have their own free will. God didn't make us slaves he gave us a choice to follow him or not. After sin entered the picture man had to sacrifice animals to get forgiveness from God. Only the High Priest could enter in the presence of God. Even then he could have no sin on him. God dwelled in a room called the Holy of Holies with was sealed off with a thick curtain. If the High Priest had sin on him, he would be struck dead because sin can't be in the presence of a perfect sinless God. Then Jesus Christ, God in the flesh, came down and was crucified on the cross. Jesus was the perfect sacrifice because he was sinless. Now we no longer have to sacrifice animals to get forgiveness of sins and a priest has no longer goes into the holy of holies to find God. When Jesus died the curtain closing off the holy of holies ripped in half because now our bodies are the holy of holies. Jesus linked us back to God once again. Now we can all experience the presence of God. All you have to do is confess your sins, believe that Jesus was the son of God, and ask God to dwell inside you.
