What is a sin?
How do you define sin?
How does the Bible define sin?
Are some sins worse than others?
If you start looking for answers to questions like this on the internet, you see lots of different view points. You will find some people that are trying to reason if being homosexual (and discussing if that is a sin) is less of a sin than killing someone. You will find lots of verses in the Bible that talk about sin. First let's try to define what sin is.
If you look the word up in the dictionary you will find that sin is an immoral act considered to be a transgression against divine law. I define sin in a much broader manner. Sin is anything that goes against the will of God.
So once you dig through what sin is and are left with discussion after discussion trying to rank sins you realize that the Bible does not give us an all inclusive list of what sins there are and which ones are the worst, and maybe some others that aren't that bad.
What you will find if you keep searching for answers in the Bible is that we are assured that we are all sinners.
FOR ALL HAVE SINNED AND FALL SHORT OF THE GLORY OF GOD - Romans 3:23
If you are reading this, you are a sinner. If you never read this, you are a sinner. But, keep reading...
YET GOD, WITH UNDESERVED KINDNESS, DECLARES THAT WE ARE RIGHTEOUS. HE DID THIS THROUGH CHRIST JESUS WHEN HE FREED US FROM THE PENALTY FOR OUR SINS - Romans 3:24
Yes, God sent his son to pay for your sins and set things right. Even though none of us deserve this grace, we all receive it if we believe in the Lord. It doesn't matter which sins you have committed, or how you rank them, or if you rank them. You have been given the same gift that the sinner next to you has been given.
God love each and every one of us with the same unconditional love, so do you really think it matters to figure out which sins are worse than others???
