Does this mean that someone who is saved never sins again? That seems to conflict with what John says.
1 John 2:1-2, KJV
My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
And Paul also says:
Romans 7:19, KJV
For the good that I would I do not: but the evil which I would not, that I do.
These Scriptures seem to say that even after being saved, people sometimes do what they shouldn't, and don't even want to do it because of their new spiritual natures, but they still do it.
Here is exactly why it's not a good idea to get into doctrine wars and throw Scripture-grenades at each other. "The Bible tells us THIS!" (kaboom) "No, it actually tells us THIS!" (more kaboom) "You're both wrong. It says THIS!" (another kaboom, and everything is in ruins.)
And that's why I like what Paul said to Timothy here:
2 Timothy 2:22-23, KJV
But foolish and unlearned questions avoid, knowing that they do gender strifes. And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient, In meekness instructing those that oppose themselves; if God peradventure will give them repentance to the acknowledging of the truth; And that they may recover themselves out of the snare of the devil, who are taken captive by him at his will.
(Yes, teach doctrine, but do it gently, not argumentatively.)
And to Titus here:
Titus 3:9 KJV
But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain.
Don't get caught up in nitpicky points of doctrine. So important, Paul said it twice.
By the way, I am not a KJV-only advocate, but I use it when discussing the Bible on a public forum. That way, even the most staunch ultra-conservative can't accuse me of using the "wrong" version. Well... given previous discussions in this thread, I suppose Catholics can, but is there much difference in these verses from the Douay-Rheims?
