When you think about sin, what is the first thing that comes to mind? Is it murder? Adultery? Maybe lying? While these are all different types of sin, sin in the Bible is defined as anything that violates God’s laws or rebels against His ways.
What Does the Bible Say About Sin?
To understand what is sin and what isn’t sin, we have to return to the Garden of Eden in Genesis. When God made the world, everything was perfect and sin was non-existent. There was only one rule in all of the world: Adam & Eve were not to eat from the tree of the knowledge of good and evil. When the serpent deceived Adam & Eve, they ate the forbidden fruit, and that’s when sin entered the world.
After the fall of man, God needed to define something important for us: what is sin and what isn’t sin. In response, God set clear boundary lines for humanity so that we would know what sin is according to the Bible. The Ten Commandments are an example of God giving humanity a list of directions on what not to do and what to do; a list of what is sin and what isn’t sin. The Ten Commandments are like God’s master list of what things are good for us and what things are bad for us.
Bible verses about what sin is show us how sin harms us, how it grieves God, and how, when we practice a lifestyle of sin, we’re partnering with the devil rather than God. But just how far does sin go? What is sin? The Bible says that lying, cheating, and stealing are all examples of sin. The scriptures also show us Bible verses about sins like lust, adultery, and sexual immorality. And even sins you might not think about: like knowing the good you ought to do, but choosing not to do it (James 4:17). Thankfully, God designed a way out for us: Jesus! God sent His one and only Son to save us from sin and give us freedom from sin.

Bible Verses to Answer the Question: What is Sin?
If you’re searching for an answer to the question, “What is sin?”, you’ll find plenty of answers in the Bible. Scriptures on sin offer us clear teachings on what sin is, how it separates us from God, and how we can overcome it through Jesus Christ.

What is original sin in the Bible? This Bible verse shows us that the origin of original sin is found in disobedience to God. Out of kindness, God gave Adam & Eve a warning about the tree of the knowledge of good and evil, so that sin would not enter the world. However, they chose to eat the forbidden fruit, and now sin is in the world because of their actions. You can think of the tree of the knowledge of good and evil as the match that lit the first spark of sin.

Why is Sin So Serious to God?
As you learn more about what sin is, you’ll begin to understand why sin is such a serious matter. At surface level, you can see how lying or adultery could lead to divorce and broken homes. But when you dig deeper, you discover that lying not only hurts others, but it grieves the heart of God…because if you think about it, a lie is what got us into this mess in the first place.
Sin is serious to God because He never intended for us to know the knowledge of good and evil. However, God desired that humans have free will. Free will means that we can choose God or we can choose evil. Each time we sin, we are choosing evil and selfish things over God.
When you pause and take a moment to think beyond the reality of what sin is and remember that God gave us Jesus to be free from sin, so much of life comes into perspective. Whatever sin habit you’re struggling with, Jesus has freedom for you!
