I've heard three different interpretations for Hebrews 6:4-6 (hypothetical view, lost salvation view, never truly saved view) but am not convinced that it teaches a really "saved" person truly "lost their salvation." NOWHERE does the Bible use the words "lose or lost salvation." According to the hypothetical interpretation, the key word in the passage is IF (verse 6). According to this view, the writer of Hebrews is setting up a hypothetical statement: "IF a Christian were to fall away." The point being made is that it would be impossible IF a Christian fell away to renew them again. That’s because Christ died once for sin and if His sacrifice is insufficient, then there’s no hope at all. The passage then presents an argument based on a false premise (that a true Christian can fall away) and follows it to its senseless conclusion that they would crucify again for themselves the Son of God.
In regards to the never truly saved view, the words,
once enlightened - which means to bring to light, to shed light upon or to cause light to shine upon some object, in the sense of illuminating it. John 1:9 describes Jesus, the "true Light," giving light "to every man," but this cannot mean the light of salvation, because not every man is saved.
The light either leads to the complete acceptance of Jesus Christ or produces condemnation in those who reject the light.
In regards to
partakers of the Holy Spirit, which describes one who shares with someone else as an associate in an undertaking. It speaks of those who are participators in sharing in, a partner in a work, office, dignity. Metochos is used elsewhere in Hebrews 3:14 in the context of believers, "For we have become partakers of Christ," so at first glance, partakers of the Holy Spirit "on the surface" would seem to support that true believers are being addressed, yet there are other ministries of the Holy Spirit that precede the indwelling of believers. It's plausible to envision an individual becoming a sharer in or partaker of the Spirit (his pre-salvation ministry, convicting of sin, righteousness and judgment to come) by temporarily responding to His drawing power intended to lead sinners to Christ. *Note that the writer of Hebrews does not state that these individuals were "indwelled by the Holy Spirit" or "sealed by the Holy Spirit" or have "received the Spirit's pledge which is the guarantee of future inheritance." Genuine believers who have believed the gospel are
sealed in Him with the Holy Spirit who is the guarantee of our inheritance until the redemption of the purchased possession/unto the day of redemption. (Ephesians 1:13-14; 4:30)
In regards to
tasted the good word of God and the powers of the age to come, they may have tasted in such a way as to give them a distinct impression of the quality and character of what was tasted, yet they still fell away. Inherent in the idea of tasting is the fact that one might or might not decide to accept what is tasted. For example, the same Greek word (geuomai) is used in Matthew 27:34 to say that those crucifying Jesus "offered him wine to drink, mingled with gall; but when
he tasted it, he would not drink it." Do we
taste into one Spirit or
drink into one Spirit? (1 Corinthians 12:13).
In regards to
fall away, in Proverbs 24:16, we read - For a
righteous man may fall seven times AND rise again, But the
wicked shall fall by calamity. Those who permanently fall away demonstrate they were not truly born again.
In Hebrews 6:7-8, we read - For the earth which drinks in the rain that often comes upon it, and bears herbs useful for those by whom it is cultivated, receives blessing from God; but if it bears thorns and briars, it is rejected and near to being cursed, whose end is to be burned. In this agricultural metaphor, those who receive final judgment are compared to land that bears no vegetation or useful fruit, but rather bears thorns and thistles. When we recall other metaphors in Scripture where good fruit is a sign of true spiritual life and a lack of good fruit is a sign of false believers (Matthew 3:8-10; 7:15-20; 12:33-35), we already have an indication that the most trustworthy evidence of one's spiritual condition is the fruit they bear (whether good or bad), suggesting that the writer of Hebrews is talking about people who are not genuine believers.
*Verse 9 sums it up for me. The writer is speaking to those truly saved (refers to them as BELOVED). He says that
even though he speaks like this concerning THOSE types of people, He is convinced of better things concerning YOU. Things that ACCOMPANY SALVATION. Thorns and briars and falling away permanently do not accompany salvation.
It's generally stated by those who believe salvation can be lost that you can get it back again, yet that would not be the case here if the writer of Hebrews was teaching a loss of salvation. Now why is it that we never find the words "lose or lost your salvation" in the Bible? That would certainly settle the issue for me. I have heard certain individuals state they know someone who was truly saved, but later lost their salvation, yet only God truly knows the heart of individuals. Certain people "on the surface" may do a good job of looking like the real deal for a while (like Judas Iscariot, who was an
unbelieving, unclean devil who betrayed Jesus - John 6:64-71; 13:10-11) yet to the other 11 disciples, he looked like the real deal,
but Jesus knew his heart. There are genuine Christians and there are "nominal" Christians. There are genuine believers and there are make believers.
*It never ceases to amaze me how the people who attack the OSAS/perseverance/preservation of the saints doctrine the most and in cynical fashion are those who teach salvation by works and ALL false religions and cults that teach salvation by works strongly disagree with OSAS, which has always been a
red flag for me.
