To all who know the true Gospel of Jesus, which is once saved always saved - cudos!
To the others try studying some basic linguistics. There is no need for me to repeat all the good discusions others have done.
Don't get confused by the ones who have perverted God's word to try imply you can ever loose your salvation. They are taking God's word out of context because they are linguistically incompetent. To say that a person, especially God would intentionally contradict Himself is beyond ignorance.
The facts are that God said that savlation is a gift and it's free from any kind of works. Therefore, you must proceed with that precept if you are going to justly interpret someone's words. If someone has established that they support the constitution of the United States and you hear them say that we need to abolish the legal system. Do you assume that they are saying they no longer believe in the law.
It would be foolish to do so and competely in accurate. It is more like that such an individual is upset with the way the constitution has been erroded and that they believe the present legal system is corrupt and needs to be abolished.
To think otherwise would open up written language to be interpreted any way that any one wanted to. It would sink written language into a state of having no meaning any longer. Even more so it would be to imply that God is literat incompetent. Since God is suppose to be perfect, these false teachers would bring him down to a state of imcomptance.
All of God's word has to be harmonious if you are going to believe in the inerrant word of God. Every scripture those false teachers use can be proven to be interpreted in error. There are many authors who have written books on this, so there is not enough room or time for me to display all of that research.
Suffice it to say that any doctrine that even one scripture contradicts, is in fact in error. But let's consider briefly one of the scriptures so badly perverted by the false teachers, which is Hebrews 10:26-31. No where is the word hell mentioned. There is no reference here to "the lake of fire," "Gehenna," "hell," "unquenchable fire," "eternal torment," or any terms commonly associated with eternal condemnation. And yet these false teachers marrily go off on there way trying to promote a false teaching that does not even reference the thing they are trying to promote.
It really boils down to these people have not actually studied the Bible for what it says but rather have gone to the Bible in ignorance and have tried to make it say what it does not.
I find these people most disgusting. At least the mormons, muslims and other religions have invented their own books to justify their belief systems. At least there is some diginity in that. But to willfully pervert and twist someone's words, it's just plain disgusting.
These false teachers need some education to offset theri literate incompentancy. Even if you choose to not agree with what is written in the Bible, you at least will show that you have some literate competance. As apposed to twisting the Bible.
In the end God has already explained why so many false teachers, don't understand the true Gospel of Jesus. It's because the preaching of the Gospel is foolishness to those who don't believe. A gospel of works, is something that most people can believe, therefore common sense should tell us that the true Gospel should be something that eveyone might find difficult to believe. Now a Gospel of pure Grace, in which all that is required is to just believe; that kind of love would be hard to believe. Which only makes the true Gospel of Jesus all the more wonderful.
Blessed be the one true God, whose love is without measure. Blessed be His name forever and ever - Amen!
