I have heard many Christians say that all sin is equal and we are all lost in this equality of sin and we need only accept Jesus' forgiveness in order to enter into eternal life and become spiritually alive.
So:
All sin is equal.
All sin is forgiven by believing in / accepting Jesus.
Correct?
Sadly brother, this popular "Christian soundbyte" simply is not Scriptural and also not true. All sin earns damnation, but not all sin is equal.
If anyone sees his brother committing a sin not leading to death, he shall ask, and God will give him life—to those who commit sins that do not lead to death. There is sin that leads to death; I do not say that one should pray for that. All wrongdoing is sin, but there is sin that does not lead to death.
(1 John 5:16-17 ESV)
Clearly, some sins are more heinous than others.
Now of course, John says earlier in this same Epistle
that we're all sinners, and we know
from Paul that the cost (wages) of sin is death. This means that unless we have someone to atone for our sins, all of us are hell bound by willing default. So in the end, unless we repent and put our trust in Christ, who will then account His righteousness to our filthiness, we will be judged by our own works during judgement day. Let's face it brother, none of us want to do this because if we start to look within honestly, things quickly fall apart. If we look at the Law, we see how much we suck (as this video quickly demonstrates):

So only by the grace of God will we be saved ultimately and even a lifetime of "little sins" earns us hell without Christ. However, there are indeed different degrees of sin. Raping and murdering, however, have not only an effect on other people, but a much more drastic one on one's own consciousness, which would indicate a huge degree of spiritual hardening.
So in short, without Christ, we're all sinners and all deserve death, but some sins are still more heinous then others. This applies to the elect as it does to the reprobate.
Why is it that so many Christians quickly back up and back peddle when we begin to discuss really heinous crimes committed by Christians? The automatic default is that these people were't "real" Christians.
Well, obviously the reason they back peddle is because they're inconsistent. But the idea of someone not being a "real Christian" is a slightly different notion. For folks who believe that once you've had a true conversion, repented and put your trust in Christ, Christ's blood justifies you and you cannot be "un-justified," aka, the "Preservation/Perseverance of the Saints" or sometimes (but perhaps inappropriately called) "once saved, always saved," then what they likely also mean here is that this person had a false conversion. I.e. they were never "saved" to begin with. Again, as John says in the same letter:
They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us.
(1 John 2:19 ESV)
So yes, some folks who say "all sin is equal" may back peddle here, but it is possible to follow Scripture where some sins are sins "unto death" and yet also accept the notion that someone may have had a false conversion and thus, may have never been saved to begin with.
As a side note, we're never to speculate on this when it comes to whether someone is elect or not. Yes, there are fruits, but we cannot know what God has in store for the person, perhaps after this hideous fall into sin they may have suffered. We can have personal assurance, but that only applies to us personally.
But if all sin is equal, why does it matter? We're all sinners and all sin is equal so why is a Christian mass-murderer accused of not being a "real" Christian? Could he not be a real Christian with a fully committed relationship to Jesus? After all, he just happens to sin but that sin is no better or worse than any other, right?
Here you're getting into what's called in theology speak, "
antinomianism." It means to be "against the law." The notion is that since one has been saved, one can get hammered drunk at the strip club every night and still be good to go because you've got you a "Get Out of Hell Free Card." This is an ancient heresy that has sadly reappeared quite a bit in some "Free Grace" circles. But as we also see (1st John is really applicable to everything your saying here) in John, someone who has a true conversion, someone who has experienced the regeneration of the Holy Spirit,
will strive to try to overcome sin, not because they are scared of damnation, but because it pains them to hurt their Father who died for the sins they continue to commit. In other words, a true conversion will produce fruit, even if that fruit is a constant up and down falling and getting back up until they die. The elect are still sinners, still suck, and will still sin. But their heart has been changed by the Spirit, and their reaction to sin is different. Oh yes, they might even fall into awful sin, but if they have been truly called, Christ will raise them back up in His own time.
In any case, you bring up great points brother and hope this helps!
