what type of sin ?
Idolatry for the Israelites. Putting trust in works for the Galatians. Not seeing Jesus as the Messiah for the Pharisees.
The kind of sin doesn't matter. If the kind of sin did matter, then you would have to wonder why God gave us so many things to follow that are not important. God does not say, "Well, this sin is not as bad, so it doesn't matter if you do it."
Paul says,
"None is righteous.
No, not one."
Jesus whole message was a message of repentance based on Matthew 4:17. Without a person seeing they are a sinner, there is no salvation. If we don't know we sin, we don't know we need to be forgiven. That is why it is sometimes appropriate to tell people they are sinners. So they can know they need forgiveness and can look to the cross for that.
