Why Eternal Security Is Not a Biblical Doctrine
By Philip A. Matthews
Eternal Security is the doctrine that simply states, "Once saved, always saved (OSAS). This doctrine teaches that once a person has been born again by trusting in Jesus as his personal Savior, i.e., "saved, he can never be eternally lost, i.e., go to hell after his life has ended, no matter how far that person may backslide or live and die in unconfessed sin after his initial belief in Christ. Eternal security claims that one act of faith in Christ at some time in a person's life guarantees heaven for them forevermore.
So, according to this doctrine, there is no way for a saved person to backslide and be lost. There is no way for you to "lose your salvation. There is no way to "fall from grace. There is no such thing as "losing out or "going back on God, with the consequence being that a person who was once saved goes to hell. There is no such thing as "apostasy. Once you are saved, you are "preserved. This is known in Calvinism as the "preservation of the saints. Sometimes it is referred to as "assurance in Christ.
God's Promises Are Conditional
In commenting on this doctrine, it should first be noted that the promises of God are all conditional. That is, God's promised benefits are given to people as they meet the conditions stated or implied within that promise. In other words, God's promises have strings attached. He does not make blanket promises that apply to everybody in every place for every time. His promises are for specific people who meet specific conditions and qualifications for the specific benefits promised.
Take John 3:16 for example. The promise is that
"whosoever believes in Him (Jesus) should not perish but have everlasting life. There is a condition here that must be met before you can receive everlasting life: You must first believe in Jesus. If (which specifies a condition) you believe in Him, then you will not perish and you will have everlasting life. But if you do not believe in Him, then you will not have everlasting life and you will perish.
Let's take another example, Galatians 6:9:
"And let us not be weary in well doing; for in due season we shall reap, if we faint not. The condition that must be met, before the promise to reap can be fulfilled, is that we must not faint. So if we faint, then it follows that we shall not reap.
But it also follows that if we have reaped, then it must be true that we did not faint. Otherwise, if we reaped and yet we
did faint, then it must be true that we will reap whether we faint or not. This makes the conditional statement absolutely useless and the verse nonsensical: we shall reap if
do not faint and we shall reap if we
do faint. No matter what we do, we shall reap. But if this be the case, then Paul's warning against fainting is meaningless and utter nonsense. Why encourage people not to faint when in actuality it does not matter if they do or they don't.
But what is the point here? The point is that, every conditional statement in the Bible”implied or direct”is what is called a "tautology. That is, it is true both ways”forward and backward. Thus, it is true that "if we do not faint, then we shall reap. And it is also true that if we
do faint, then we will
not reap. It is also true that if we have reaped, then we must not have fainted, as well as, if we did not reap, then we must have fainted. In logic, these statements condense into this:
"We shall reap if and only if we do not faint.
The Bible Is Logically Valid
Thus, the conditional, "if-then-type statements of the Bible are tautological. If they are not, then many contradictions, untruths, and nonsensical statements result. This principle of logic must be used throughout the New Testament regarding all conditional statements and promises. The "If always means "If and Only If. If it does not, then the conditional statement becomes unconditional, thus stripping the statement of all sense and meaning.
Let's take one more example, one much more directly applicable to the issue at hand, eternal security. Second Peter 1:10-11 (NIV) reads:
"Therefore, my brothers, be all the more eager ["diligent KJV] to make your calling and election sure. For if you do these things, you will never fall, and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ. Exactly what things is Peter telling them to do? Obviously, he means the things he listed in verses 5 through 9:
"Add to your faith virtue; and to virtue knowledge; and to knowledge temperance; and to temperance patience; and to patience godliness; and to godliness brotherly kindness; and to brotherly kindness charity [love]. These are the "things they are to add. Then in verse 8 he states that if "these things be in you and abound, you will not be unfruitful. In verse 9, he warns that if you "lack these things, you are blind, cannot see afar off, and have forgotten that you were purged from your sins. Finally in verse 10, he says that "if you do these things, you will never fall¦and receive a rich welcome¦
Now this "if is an "if and only if. The promise is that you will never fall and you will receive a rich welcome
if and only if "you do these things. This rules out the possibility that you will never fall and you will receive a rich welcome
without doing "these things. It must be true that if you do not do these things, then you
will fall. If you do not do these things, then you
will not receive a rich welcome. If it were possible for them to
not do these things and still receive a rich welcome, then it makes no sense to warn them about it at all.
Applied to eternal security, this principle thus completely rules out the possibility of somebody getting saved, then going back out into sin and failing to do "these things, but still they never "fall and still they "receive a rich welcome into heaven. Anybody who gets saved, then fails to grow in grace, instead choosing to revert back to his old sinful lifestyle, has definitely fallen and will not be welcomed into heaven. If they make it to heaven anyway, living their sinful unrepentant lifestyle, then 2 Peter 1:10-11”and most of the rest of the New Testament”is a sham and a mockery.
There are many other such scriptures to which this principle of "if and only if applies. Revelation 2:10 promises, "Be thou faithful unto death, and I will give thee a crown of life. This
must mean, "I will give you a crown of life
if and only if you are faithful until death. If you are not faithful until death”if you quit believing, if you quit doing the Lord's will, quit obeying and following His word”then it is pretty obvious that I will
not give you a crown of life. If you could get this crown of life without being faithful until death, then it would not make sense for Jesus to hold this out as some kind of reward for faithfulness and good behavior.
In Revelation 3:1-5, Jesus speaks of some Christians and a church that has been spiritually alive (saved) but are "about to die (NIV). He states why: "I have not found your deeds complete in the sight of My God. However, He finds that a few Christians there have not "soiled or "defiled their garments, i.e., do not have sin in their lives. These He promises will "walk with me, dressed in white, for they are worthy. Then He promises:
"He that overcomes [i.e., maintains their deeds and lives of holiness] will, like them, be dressed in white. I will never blot out his name from the book of life, but will acknowledge his name before My Father and His angels. So He promises to do three things”dress them in white, not blot out their names, and acknowledge them before God”
if and only if they will overcome. What if they do not overcome? Then it logically follows that He
will not dress them in white, He
will blot out their names from the book of life, and He
will not acknowledge knowing them before His Father. The promise is to overcomers only. What could be more plain and logical?
There is one more of these conditional statements found in Hebrews 3:14 (KJV): "For we are partakers of Christ, if we hold the beginning of our confidence steadfast unto the end. In other words, we are partakers in Christ if and only "if we hold firmly till the end the confidence we had at first (NIV). Obviously, if we do not hold that first confidence, we will not be partakers in Christ. The promise is not just to everybody, but only to those who hold to their first confidence. Paul was writing to some Christians that were being sorely tested and persecuted, and were tempted to give up. Those who let go of their faith in Christ would lose their participation and fellowship with Him. This concept Paul repeated in chapter 10:32-39. He warned those Christians not to be of "those who shrink back and are destroyed, but of those who believe and are saved."
