Adam and Eve’s act of sin is often known as “The Fall”, and the results of those early moments of humanity have affected every generation since. Here are a few of the ways that sin has impacted mankind:
At one point, Adam and Eve could walk freely in the presence of God. After they had sinned, however, they had become ashamed of their nakedness and hid from him (Gen. 3:7-10). Humans have never been able to stand in the presence of God in quite the same way since.
Genesis 3 lists a few punishments that humanity would receive as a result of this sinful act, but one of the most significant is death (Gen. 3:19). The book of Romans says that the wages of sin is death (Rom. 3:23), meaning that our sin will receive its rightful payment in due course. Because Adam and Eve had chosen not to trust God, death would affect every single person, animal, and living thing (Rom. 5:12-19) in such a way that all fall short of the standards that God set for us (Rom. 3:23). Without proper payment for sin, that punishment would be eternal.
The Bible says that without the shedding of blood, there is no forgiveness of sin (Heb. 9:22). The only acceptable punishment for sin was death, but God allowed humans to sacrifice animals as a substitutionary payment in their place. Through an animal sacrifice mankind could be granted forgiveness for past sins; however, this act would have to be repeated every time someone sinned again. This continued for thousands of years, right up until the time of Jesus, when the greatest event in the history of the universe would change everything.
