The scripture in these passages is the story of Cain and Abel. Cain was the first murderer of the world in this text. The question asked of many is why wasn't Cain's sacrifice pleasing to God. Reference is given in Hebrews 11 by the words "by faith". Without faith it is impossible to please God. God gives Cain a warning of if he continues on the path of sin, it will dominate his life moving forward. God gave Cain the opportunity to repent of his sin. Cain instead puts the blame on God, for we often are selfish and try to justify our actions. Scripture tells us, "The wages of sin is death." Moving forward in the scripture, Eve gives birth to Seth. God always restores what has been taken away. Illustrates God gives hope to a fallen world.
