Since all evil acts come down to disobedience against god, are all evil acts equivalent? Is no sin worse than any other sin? If one sin is worse than another sin does that imply that one act can be more disobedient than another act? Is sin and/or disobedience absolute or does it have degree?
There are two primary views of this.
Unfortunately, they're both pretty sound beliefs.
All sins are not equal
There are many verses to back up this belief that all sins are not equal. Here are some of them:
All sins are equal
The idea that "all sins are equal in God's eyes" comes from the idea that any one sin will lead to death. If we commit a single sin, we are as guilty (in God's eyes) as if we had committed the worst sin--regardless of which sin we committed.
It's based on the idea that God's holiness is so extreme, that even one transgression is greater than he can accept. This idea is supported with two key verses
The argument goes, therefore, that if even the smallest sin prevents us from attaining the perfection that God calls us to seek, then that one single sin is as great as the worst sin.
We can reconcile these two seemingly opposing viewpoints: we can clearly see that some sins are greater than others, but that any sin will prevent us from going to heaven without the saving grace and sacrifice of Jesus.
Essentially, any one sin is sufficient to keep us from God, but all sins are not the same.
There are two major Bible passages that I can think of, which some use to suggest not all sins are equally bad.
The way I see it, verse 18 makes the distinction between sin and keeping on sinning, also known as living in sin. Which is not a difference between sins, but other circumstances.
Blaspheming against the Holy Spirit is a matter of another question. I tend to interpret it as ultimately refusing salvation, which would quite obviously make a person unsalvageable. Using that interpretation, I wouldn't say there's a difference between graveness of sins here, either.
So from these passages, I wouldn't draw any big conclusions. Generally, the Bible shows sin as just sin, not in different levels of wickedness.
Of course, for purposes of human relationships, there certainly are different severities of sins. What I say above focuses on the relationship between us and God: we deserve to be damned for our sins, everybody. It doesn't matter which sins we commit. Only Christ matters.
No, all sins are not equal.
You as a human being understand that killing somebody is more of a sin then stealing $5 from their wallet. So could you ever assume that God sees all sin as being equal?
God clearly states in more then one instance, that He will repay the people according to what they have done.
God is perfect, God is just, therefore God is a perfect judge that will repay all people exactly according to what they have done.
Yes all sin is equal in our relationship with God, because not a single sin that you have done has ever affected God.
As @dancek pointed out, there are also references in the bible that suggest that not all sin is equal.
No, not all sin is equal in God's eyes
This is a cop-out. This premise suggests that God is not perfect and that you don't have to worry about your sin because it's all the same to God. Instead, God clearly states again and again that He will judge you accordingly.
If all sin was equal in God's eyes, then God would surely pass down the same judgement to all people, regardless of their iniquity. But as it is said, God will judge the people according to what they had done.
@Richard, Yes a single sin makes you unrighteous and a single sin will submit you to the subjection of God's judgement, but that does not mean that all sin is equal.
Many scriptures were quoted, but the levels of sin has not been explained. I will not add scriptures, just name the levels. As you go up in levels it gets more difficult to break with it and the small ones lead you into the trap of the bigger ones.
I will start at small
I see positions supporting both yes and no but there is a third option to all situations: it doesn't matter. The Bible does not specifically say sin is by degrees nor does it say sin is not by degrees. You cannot build a doctrine on what may be isolated texts taken out of context in either direction. I do see in the scripture where there is an unforgivable sin but that is not all that important to this discussion.
The vast majority of sin has the same outcome for the believer death. It doesn't really matter if certain sins cause you to die faster because regardless of how little or how much it still displeases God. Even the smallest sin would have sent Christ to the cross.
In Christ all sins are forgiven and to maximize, minimize or equalize sin is to distract from the Saviour of sin who washes us clean by his precious Blood when we accept the salvation He offers in faith. To give into any sin regardless of whether you think it is equal or not is treason and will result in your eventual death when you will promptly go to heaven and be rewarded and corrected.
Is it a misconception and misunderstanding that "all sins are equal". Of course there are different levels of sin!
"All wrongdoing is sin, and there is sin that does not lead to death" 1 John 5:17
Not all sin leads to death. Not all sins are forgivable either (see the unforgivable sin)
Some sin is sin of Omission (as opposed to commission)
"If anyone, then, knows the good they ought to do and doesn't do it, it is sin for them." James 4:17
-- Sin is deviating from what God would do. It is not just violating a law or a rule. It is the state of not being one with the spirit.
Well, from a human perspective yes. Because the consequences of some sin actions affect more than the one person. And it's quite easy to make a judgement on which sin is worse.
But from an eternal perspective it doesn't actually matter.
Ultimately, it doesn't really matter which sin is worse than another. What matters more is "what are you doing about Jesus?"
If you haven't believed in his salvation then you won't care if you were a good person when you were alive on the earth 1000 years from now, not with God in heaven but burning in hell. It's true, but it's not good news.
The good news is that we are saved by grace through faith. In other words, believe on Jesus and confess it. It's available to all who would do just that.
