But receiving the Holy Spirit that’s guaranteed salvation right?
2 Corinthians 1:22 - who also has
sealed us and given us the Spirit in our hearts as a guarantee.
Ephesians 1:13 - In Him you also trusted, after you heard the word of truth, the
gospel of your salvation; in whom also, having
believed, you were
sealed with the Holy Spirit of promise, 14 who is the
guarantee of our inheritance until the redemption of the purchased possession, to the praise of His glory.
Ephesians 4:30 - And do not grieve the Holy Spirit of God, by whom you were
sealed unto/for the day of redemption.
What if they don’t repent and bear the fruits of righteousness?
Then we demonstrate that we are not true believers and were not born again from the start.
“For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost, And have tasted the good word of God, and the powers of the world to come, If they shall fall away, to renew them again unto repentance;
In regards to
renew them again unto repentance, this does not specify whether the repentance was merely outward or genuine accompanied by saving faith. They have in some sense "repented," there may be sorrow for sins and an attempt to turn from them (moral self-reformation) that non-believers can experience. There is repentance that falls short of salvation, which is clear from Hebrews 12:7 and the reference to Esau, as well as the repentance of Judas Iscariot in Matthew 27:3. Paul refers to a repentance “without regret that leads to salvation,” which shows there is a repentance that does not lead to salvation. As with “belief/faith”, so too with “repentance,” we must always distinguish between what is substantial and results in salvation and what is spurious. Renew them again "unto salvation" would be conclusive evidence for your argument.
In regards to
partakers of the Holy Spirit, the word translated “partaker” can certainly refer to a saving partaking in Christ, as we read in Hebrews 3:14, yet it can also refer to a less than saving association or participation. See Luke 5:7 and Hebrews 1:9 - "comrades, companions," which describes one who shares with someone else as an associate in an undertaking. These Hebrews who fell away had obviously in some aspect shared in the ministry of the Holy Spirit, but in what way? There are other ministries of the Holy Spirit which precede receiving the indwelling and sealing of the Holy Spirit, which only genuine believers receive..
Those who fall away absolutely could have been affiliated closely with the fellowship of the church. Such people certainly may have experienced sorrow for sin, heard and understood the gospel and have given some assent to it and have become associated with the work of the Holy Spirit while around believers and have tasted the heavenly gift and the powers of the age to come. They may have been exposed to the true preaching of the word of God, yet have
simply tasted and stopped there. People who have experienced these factors may be genuine Christians, yet these factors alone are not enough to give conclusive evidence that the beginning stages of the Christian life (repentance unto life, regeneration, salvation, justification, etc..) have taken place for those who fell away. The experiences in Hebrews 6:4-6 are all preliminary to those decisive beginning stages of becoming a Christian,
yet some draw back to perdition after receiving the 'knowledge' of the truth and do not believe to the saving of the soul, as we saw in (Hebrews 10:26-39).
These certain individuals who fall short of obtaining salvation certainly may have become partakers of the Holy Spirit in his pre-salvation ministry, convicting of sin and righteousness and judgment to come by tasting the good word of God and temporarily responded to His drawing power which is intended to ultimately lead unbelievers to Christ,
yet the writer of Hebrews does not use conclusive terms that these individuals were "indwelled by the Holy Spirit" or "sealed by the Holy Spirit" 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 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 merely "taste" into one Spirit or
drink into one Spirit? (1 Corinthians 12:13)
seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
For the earth which drinketh in the rain that cometh oft upon it, and bringeth forth herbs meet for them by whom it is dressed, receiveth blessing from God: But
that which beareth thorns and briers is rejected, and is nigh unto cursing; whose end is to be burned.”
Hebrews 6:4-8 KJV
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 metaphor relating to agriculture, those who receive final judgment are compared to land that bears no vegetation or useful fruit, but rather bears thorns and thistles. We read in scripture that 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) so we have an indication that the 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 and are not fruits worthy of authentic repentance.
