In these days of very difficult and possibly even trying events involving what could be the closing in of the Great Tribulation, I want us to revisit the thinking concerning eternal security.  First, I want you to know that there is no sin except for one that can take you out of the hand of God once you are In it. That one sin, I will discuss a bit later (it is called the unforgivable sin), but I want you to consider the warnings of scripture that cannot be ignored for the Christian. Jesus within His message to His disciples in Matt. 24, told them to not be deceived by what is coming to the earth in what He was describing as the end that was coming. And when He prayed His prayer to His Father recorded in John 17, He made clear that He was just as concerned for us who would believe beyond them in their day.  So I make it a point in my life to listen to what Jesus taught His closest chosen ones.   

How and why did He teach them (for us) certain things that go against eternal security?

To the seven churches in Revelation 3, He says to one of those churches that a change in their life is necessary:

Revelation 3:2  Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God. (KJV)

It certainly seems that if these things are acted upon and they are overcome he will not blot their name out of the book of life. 

Revelation 3:5  He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels. (KJV)

Now. Maybe that warning is only to cause us to make our calling and election sure.  Maybe they were not yet saved?  But that really does not make sense, because He stated in Rev 3:2. “Wake up then and strengthen the things which remain which are about to die.” What could possibly die that would remove us from the book of life? There is only one thing that really matters, and it is a He.

What does all this say to us?  Paul tells us to neglect not so great a Salvation. 

Also, James in his only epistle tells us at the very end of it that if any brother strays from the Truth (Jesus is Truth), and another brother brings that one back from his fall, the result will be the saving of his soul from death. 

James 5:19  My brethren, if any among you strays from the truth and one turns him back,  20  let him know that he who turns a sinner from the error of his way will save his soul from death and will cover a multitude of sins. (NASB1995)

Some say will this is physical death, but physical death they teach is: (for the Christian) a graduation into paradise) why would James be so concerned about that?  Why would he end his epistle with that if it did not have grave consequence. 

Obviously a person is not going to save his soul by saving everyone around him.  James obviously is speaking of the one who falls as the one, who will be saved from losing the eternal life that he had already once possessed. 

Now for the unforgivable sin. Jesus also had told us that if we deny Him that He will deny us. Remember, I’ve told you this before, but Paul also affirmed that message when he told Timothy that if we deny him, he will deny us. The unforgivable sin, seems then to be the denial of the One Who bought us. Allowing sin to master us can lead us there. To deny Him is not an easy thing to do, but it requires the loss of our faith in Him. A man walking in faith, cannot deny the Lord.  Our faith is built upon what He did for us, but if we deny Him, we obviously have a lost faith in what He did for us. 

As believers: If we have sinned, then we repent of that sin. Some days I have to do that more than once. But I always hold to the fact that his blood will cleanse me from all my sin. By saying that we can lose our Salvation, this does not mean that He is not always faithful. What it means is that we are as free will agents capable of losing faith.  But being unfaithful is even forgivable so long as we do not follow it do its ultimate conclusion. That being the denial of our Lord.

Here is an argument also supporting what I have concluded here.  I believe this to be the teachings of scripture:

Is ‘once saved always saved’ a biblical teaching?

The opposing argument against what I believe to be scriptural follows here:

No, dear Christian — you cannot lose your salvation. Ever

So was Jesus wrong in telling us that a denial of him would lead Him to deny us?  Or was He just playing with our minds when He stated that if we were to overcome in the area pointed out that He would not blot our names from the book of life?  As free will agents, we cannot afford to neglect so great a salvation.
