This is your human heritage. God knows that you can't be perfect. And God also said that all sin must be punished. There is no action, Scientists say, without an equal and opposite reaction. There is no 1 st Degree and misdemeanor sins.
All sin is punishable by death.
That means that if you do the smallest sin, you will end up in Hell. Well, as unfair as it sounds, there is a way out. Jesus Christ came to Earth as a real flesh and blood human being, but also as God in person. Only God could live the perfect, sinless life, and Jesus did. Since Jesus earned his way into Heaven, he was worthy of paying the price for the world's sin.
