God created everything good.But because Adam and Eve ate of the forbidden fruit,sin came upon the Earth. Before Jesus came to Earth, people had to make animal sacrifices to ask God for forgiveness. However, these sacrifices never were sufficent. So, because, "God so loved the world that he gave his only begotten son that whosover believith on him shall not perish but have eternal life." John 3:16. Now, if we just believe on Jesus, that he died for us, we may inherit the kingdom of heaven.
