One passage indicates that all sins are equally bad:
James 2:10-11 English Standard Version
For whoever keeps the whole law but fails in one point has become guilty of all of it. 11 For he who said, Do not commit adultery, also said, Do not murder. If you do not commit adultery but do murder, you have become a transgressor of the law.
John 3:15 English Standard Version
Everyone who hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.
But in other verses, it is taught that there are levels of sin:
When Jesus spoke of his second coming and judgment, he warned that among those deserving punishment some would be beaten with many blows and others with few blows (Luke 12:47-48). He also reserved His most fierce denunciations for the pride and unbelief of the religious leaders, not the sexually immoral (Matthew 23:13-36).
And then there is this:
Matthew 12:31-32 English Standard Version
Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven. 32 And whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.
So, if you blaspheme against the Spirit, you may as well throw in the towel. Your just fucked.
And then there are those who will say that I just do not know how to interpret the verses.
