Eternal Security and 1st John 5:16 "Sin unto death"

1st John 5:16 says,

"If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it."

Those that believe you can lose your salvation will appeal to this verse. I will not spend much time here as anyone that would simply read what it says here will realize that loss of salvation is impossible by the mere wording.

Think about this, if "death" represents "spiritual death" and if "life" represents "spiritual life" then you have a really problem. I will rewrite this verse and see if you can now see why teaching that this verse refers to loss of salvation is impossible.

"If any man see his Christian brother sin a sin which is NOT unto spiritual death, he shall ask, and he SHALL give him spiritual life for them that sin NOT unto spiritual death. There is a sin unto spiritual death: I do not say that he shall pray for it."

Did you catch that? Why would you have to ask God to give spiritual life to a man that did not commit the sin unto spiritual death? It is clearly worded that this brother did not commit a "sin unto death" so if the "sin unto death" is the loss of salvation then this man didn't lose it but why does his brother then need to ask for spiritual life and this man will get it?????? How can he give him life when he didn't commit the sin unto death??? Do you now see the problem of making this the loss of salvation? This is an example of people desperately wanting a verse to read that one can lose their salvation. How they can be so careless and deceitful to God's word is beyond me.

If you take this also to their logical conclusion then you can pray for "spiritual life" for someone and God will give it apart from believing. You can't get around the words here. If you teach that this is spiritual life we pray for then somehow our prayers can impart spiritual life and we know the Scriptures do not teach that.

It amazes me as to why people that believe you can lose your salvation are so quick to make "death" and "life" to mean "spiritual death" and "spiritual life" and will not even question if "physical death" and "physical life" could possibly be the meaning instead. We do have verses where believers had sinned and died for it as the consequence. In 1st Corinthians 11:30, it says,

"For this cause many are weak and sickly among you, and many sleep."

The specific Greek word for "sleep" here was to believers that have died in the Lord. It is reserved for those that died as a believer. Paul makes it clear in the next couple verses that God will chasten those that do not judge themselves and clearly such will not be condemned with the world.

Clearly 1st John 5:16 has a Christian brother in view that is sinning. If a brother is asking on behalf of another brother for life even though this other brother clearly has not sinned a sin unto death because he is still "alive" then he will give him life.
