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,
If they shall fall away, to renew them again unto repentance; 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.
But, beloved, we are persuaded better things of you, and things THAT ACCOMPANY SALVATION, though we thus speak.
Go on to verse 17 of this chapter…
Wherein God, willing more abundantly to shew unto the heirs of promise the immutability of his counsel, confirmed it by an oath: That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us: Which hope we have as an anchor of the soul, both sure and stedfast, and which entereth into that within the veil; Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchisedec.
The word “partake” in this verse is to receive of the Holy Spirit such as a miracle, healing, an answer to prayer. (Notice how this verse does not say regenerated by the Holy Spirit.)
The Greek word in this verse for “Partake” metochos which means to share in benefits of an association with but not necessarily to be born of the Holy Spirit. While all Christians do partake of the Holy Spirit not all who partake of the Holy Spirit are Christians. The Greek word translated “partakers” can mean from a deep and abiding commitment to a loose knowledge of someone or something.
Since it is not made perfectly clear to us we must therefore rely on other scriptures. We must always compare scriptures with scriptures in rightly dividing the truth. Notice how these in this scripture bare thorns and briers.
Jesus said that a corrupt tree bares corrupt fruit but a good tree CANNOT bring forth bad fruit. A tree bears fruit of its own kind. “…a good tree does not bear bad fruit, nor does a bad tree bear good fruit. For every tree is known by its own fruit. For men do not gather figs from thorns, nor do they gather grapes from a bramble bush. A good man out of the good treasure of his heart brings forth good; and an evil man out of the evil treasure of his heart brings forth evil. For out of the abundance of the heart his mouth speaks.” Luke 6:43-45
If you abide in My word, you are My disciples indeed. And you shall know the truth, and the truth shall make you free.” John 8:31-32
“What fruit did you have then in the things of which you are now ashamed? For the end of those things is death. But now having been set free from sin, and having become slaves of God, you have your fruit to holiness, and the end, everlasting life. For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.” Romans 6:21-23
The Bible tells us that we are new creatures in Jesus Christ and are predestined to be conformed to the image of Jesus Christ.
Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. 2 Corinthians 5:17
“For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.” Romans 8:29
The fruit of the Spirit in a Christian’s life is proof of having received Jesus Christ and being born again.
You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? Even so, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Therefore by their fruits you will know them.” Matthew 7:16-20
“Therefore I say to you, the kingdom of God will be taken from you and given to a nation bearing the fruits of it. And whoever falls on this stone will be broken; but on whomever it falls, it will grind him to powder.” Matthew 21:43-44
“Brood of vipers! Who warned you to flee from the wrath to come? Therefore bear fruits worthy of repentance…” Luke 3:7-8
“For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end. “Hebrews 3:14
Who is he that turns back to perdition and has no confidence in the salvation of Jesus Christ? Those who partook of the things of God but did not become born again and had no fellowship with the Holy Spirit, they fell away because there was no truth in them, for as scriptures declare, “Every one that is of the truth heareth my voice.” John 18:37
Can a true Christian loose salvation? NO! Those who turn back to perdition bearing bad fruit are hearers. When persecution or tribulation comes because of the word of God’s sake these hearers fall back because they tasted of the Holy Spirit’s good things to come but were never born again of the Holy Spirit. They did not receive the divine nature of God and were not made heirs of Jesus Christ’s righteousness.
