What is the Difference Between “Trespasses” and “Sins”?
Ephesians 2:1 says that we were formerly dead in trespasses and sins.
What’s the difference between trespasses, and sins?
Trespasses and sins are really synonyms.
In the Bible, such words as “trespass”, “iniquity”, “offence”, “wickedness”, and “sin” all describe the same thing – rebellion against God.
Specifically, I John 3:4 says, “Whosoever committeth sin trangresseth also the law: for sin is the transgression against the law.”
And like “transgress”, the word “trespass” underscores that we are walking on a path that we ought not walk on. We are going down our own way rather than doing it Christ’s way. But it’s still a synonym for sin.
Jesus is LORD! 
If that is the case, then why is there one sacrifice for sin (Leviticus 4), and another for trespass (Leviticus 7)?
