Through the account of Cain and Abel we see how quickly the curse of sin took hold of mankind and the damaging effects that came along with that. These effects lead to Cain murdering Abel, however, his sin did not begin there but grew into Cain murdering his brother, Abel. Unfortunately we see the same progression in people's lives today. We don't have to take the same route as Cain. With confession and repentance there is forgiveness in Jesus. Not only that, the Church can be there for each other when we fall into these sins.
