Since you don't see a distinction between preaching Christ according to prophecy vs according to mystery,
I've told you; I don't understand what you mean by that.
you will naturally think that, as long as one preach the cross, he is preaching the same Jesus as Paul, which doesn't follow.
Are you telling me now that there is more than one Jesus??
This gets worse.
I will just give you one example from 1 John to exemplify, 1 John 3
6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
10 In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.
If you are willing to accept what John is teaching there literally, without reading Paul into the passage, this doctrine will put you in bondage.
How?
Let's look at this more closely.
6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
John says here that if we abide in Jesus we will not continue to sin.
Well no one's perfect. John has already said that "if we do sin, we have One who speaks to the Father in our defence", 1 John 2:1, if we confess our sins God will forgive us, 1 John 1:9, and that if we claim to be without sin, we are deceiving ourselves, 1 John 1:10.
So unless he is contradicting himself, he means something else.
7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
Is someone righteous because they do works of righteousness, or do they do works of righteousness because they are righteous?
What does John mean by "doeth righteousness"? Good works?
A person doesn't even have to be a Christian to do good works; atheists and those of other religions so them, found charities and hospitals, raise money and so on.
8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
Yes, Jesus came to destroy the works of the devil - prophesied in the Garden of Eden, Genesis 3:15.
Anyone who deliberately and continually sins is of the devil. But no Christian is perfect; if we were, that would mean that we did not need a Saviour, 1 John 2:1-2.
9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
Anyone who is abiding in God will not deliberately sin; they will not wake up thinking "how can I rebel against God and do evil today". They will love God and want to serve him, not rebel and deny him.
10 In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.
If you are willing to accept what John is teaching there literally, without reading Paul into the passage, this doctrine will put you in bondage.
No, it seems that you believe that "doeth righteousness" means that we have to continually try to do good works to be saved. It doesn't, and John does not teach that.
That's why we need to look at the WHOLE of Scripture to understand what is being said, rather than picking out one verse, taking it literally and then deciding that the author is saying something that he's not.
If you believe the Bible - all of it - is the inspired word of God and is inerrant, then it does not contain mistakes or contradict itself.
If any of us find verses that appear to contradict what has been said before, the misunderstanding is with us, not Scripture.
Of course if people don't believe that, then they will pick and choose the parts of the Bible that back up their ideas. That's why there are so many cults around - the leader has formed certain ideas based on a small part of Scripture and ignored the rest of it. And they usually produce their own book "to help people understand the Bible", but which, in fact, only explains their ideas.
And I've already said that not everything in the Bible is meant to be taken literally.
