Accepting the truth of God's word about eternal security does not mean you can sin without consequence. That's a distorted view of God's grace, and is not what the doctrine of eternal security leads to. A complete understanding of scripture teaches that the child of God is under divine discipline when he sins(please see my answer to Fred's question about David), and can sin unto death if he does not confess and get back in line. But, in the end:
1CO 3:14 If any man's work which he has built upon it remains, he shall receive a reward.
1CO 3:15 If any man's work is burned up, he shall suffer loss; but he himself shall be saved, yet so as through fire.
This is where you're mixing two different judgements and mistaking them for one judgement. After you pass your first judgement at the saved throne of God. Then you are judged for your works. And because works cannot save you, works cannot condemn you as well. This is why you can be purified through the fire that burns up your works. This is because you have already been written in the book of life. Because Christ's blood blotted out your sins.
The reason you even get to the second judgement is because you past the first one. This is why the works judgement is different from the salvation one. And it all has to do with the blood of Christ blotting out your sins. Christ's blood allows sin to be blotted, which is what gets you into heaven. But, Christ's blood does not blot out our works. So your works have to be tested to see of what nature they are.I'm going to explain this in detail, but keep it simple:
1) What was used as an atonement for sin before christ? A goat was considered a sin offering,
2) What is now considered the sin offering? The "Lamb of God". Christ.
And what is the difference between the two?
1) The goat offering is part the old convenant with God.
2) The Lamb of God is the new convenant with the Son of God.
This is why Christ is called: The Lamb of God.
With me so far?
-----------------------------When we reject the new convenant:
The spueing out of the body of Christ. Only the old convenant is left. The goat convenant. Problem is, it is no longer the atonement for sin. Being covered by the blood of Christ requires you to be in the body of Christ. Why? When your in the body, His blood flows around you and surrounds you. And everything is fine as long as you stay there.
But, when you deny Christ, you are spued from the body. The blood of Christ, no longer surrounds you. And when you go from the new convenant (being spued from the mouth), you end up in the old convenant. Don't believe me?
mt 25:33 And he shall set the sheep on his right hand, but the goats on the left.
How do you think Goats end up in front of the saved throne?
And why do the goats get thrown into the lake of fire?
heb 10:4 For it is not possible that the blood of bulls and of goats should take away sins.
They stood before God with their sins intact, and is why they were cast into the lake of fire.
The reason this is said, is again, the old convenant is no longer in effect
. This is why this verse is worded this way:
gal 5:4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
Being justified by the law, is the old law of atonement for sin. Here it shows that when you fall from one convenant, you end up in the other.
If one convenant has no effect
, then the other is the only one left. This is why this verse is worded the way that it is:
jn 10:29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
Who's hand? Not Christ
, which stands for the new convenant, but God the father which stands for the old convenant. If that verse would have said: "My Hand", then it would have been a reference to Christ and the new convenant.
So when we are spued from the mouth of Christ (the new convenant) we fall into the old. But in each convenant, we are still in God's hands on judgement day. And is why we will all still be judged at the saved throne. Both goats (those who rejected christ) and sheep (those who kept the convenant, or came back to it*).
And it will only be those at the great white throne who get judgement that is seperate, because they were never in God's hands. So they can't be taken out of, what they were never a part of. To be a part of something also means to leave it, you have to depart from it. And this is why this verse is worded this way.
mt 7:23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
The reason God says: "depart from me",
is because they were in God's hands. As the verse that OSAS uses to confirm what they believe. But remember, it is not Christ that has the hand control, it is God the Father. And this is made clear in that very verse. And when God releases them from His hand, it still confirms that verse. For God is not a man, so removal of them is not done by man. It is done by God, and is the reason the goats will say: But I did all these things in your name? Whos' name? Christ's name is who they were supposed to do it in. For we are under the new convenant, not the old. So when they say this, they are confirming who they thought the convenant was with. And when God says: I never knew you, God is also confirming who the convenant was supposed to be with (His Son). Which also confirms this verse:
jn 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me (Christ speaking).
God the Father confirms this as He casts the goats into the lake of fire. And God's word even confirms who the convenant is with in this verse:
rev 21:27 And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb's book of life.
Who's book of life? The Lamb's book of life. Not God's. Here again it confirms who's convenant we have to be with. If we reject it. we are cut off because of what Christ says: No one cames to the Father, but by me.* Now, can someone come back from the old convenant to the new?
19 Brethren, if any of you do err from the truth, and one convert him;
20 Let him know, that he which converteth the sinner from the error of his way shall save
a soul from death, and shall hide a multitude of sins.
Remember, the word brethren means believer. So if a believer errs from the truth (becomes a goat), and one convert him back from the error of his way. Instead of his sins being intact (and shall hide a multitude of sins) in front of God. This person will have "saved" a soul from death.
What is considered death of a soul?The second death:
rev 2:11 He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death
rev 20:6 Blessed and holy is he that hath part in the first resurrection: on such the second death
hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
rev 20:14 And death and hell were cast into the lake of fire. This is the second death.
rev 21:8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death
Is hell and the lake of fire different? Read revelation 20:14 above.
Added: You'll need to read this a couple of times to get it's meaning.
