Do these not say that it is indeed possible for someone who was come to the knowledge of Christ to fall away?
This is a time saver for me to copy and paste some, but it should help.
2 Peter 2:20
For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
[For if after they have escaped the pollutions of the world] This does not necessarily mean that they had been true Christians, and had fallen from grace. People may outwardly reform, and escape from the open corruptions which prevail around them, or which they had themselves practiced, and still have no true grace at heart.
[Through the knowledge of the Lord and Saviour Jesses Christ] Neither does THIS imply that they were true Christians, or that they had ever had any saving knowledge of the Redeemer. There is a knowledge of the doctrines and duties of religion which may lead sinners to abandon their outward vices, which has no connection with saving grace. They may profess religion, and may KNOW enough of religion to understand that it requires them to abandon their vicious habits, and still never be true Christians.
[They are again entangled therein and overcome] The word rendered "entangled," emplekoo (NT:1707) from which is derived our word "implicate," means to braid in, to interweave; then to involve in, to entangle. It means here that they become implicated in those vices like an animal that is entangled in a net.
[The latter end is worse with them than the beginning] This is usually the case. Apostates become worse than they were before their professed conversion. "Reformed" drunkards, if they go back to their "cups" again, become more abandoned than ever. Thus, it is with those who have been addicted to any habits of vice, and who profess to become religious, and then fall away. The "reasons" for this may be:
(1) that they are willing now to show to others that they are no longer under the restraints by which they had professedly bound themselves;
(2) that God gives them up to indulgence with fewer restraints than formerly; and
(3) their old companions in sin may be at special pains to court their society, and to lead them into temptation, in order to obtain a triumph over virtue and religion.

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,
[For it is impossible] It is needless to say that the passage here (Heb 6:4-6), has given occasion to much controversy, and that the opinions of commentators and of the Christian world are yet greatly divided in regard to its meaning. On the one hand, it is held that the passage is not intended to describe those who are true Christians, but only those who have been awakened and enlightened, and who then fall back; and on the other it is maintained that it refers to those who are true Christians, and who then apostatize. The contending parties have been Calvinists and Arminians; each party, in general, interpreting it according to the views which are held on the question about falling from grace. I shall endeavor, as well as I may be able, to state the true meaning of the passage by an examination of the words and phrases in detail, observing here, in general, that it seems to me that it refers to true Christians; that the object is to keep them from apostasy, and that it teaches that if they should apostatize, it would be impossible to renew them again or to save them. That it refers to true Christians will be apparent from these considerations.
(1) Such is the sense which would strike the great mass of readers. Unless there were some theory to defend, the great body of readers of the New Testament would consider the expression used here as describing true Christians.
(2) The connection demands such an interpretation. The apostle was addressing Christians. He was endeavoring to keep them from apostasy. The object was not to keep those who were awakened and enlightened from apostasy, but it was to preserve those who were already in the Church of Christ, from going back to perdition. The kind of exhortation appropriate to those who were awakened and convicted, but who were not truly converted, would be "to become converted;" not to warn them of the danger of "falling away." Besides, the apostle would not have said of such persons that they COULD NOT be converted and saved. But of sincere Christians it might be said with the utmost propriety, that they COULD NOT be renewed again and be saved if they should fall away-because they rejected the only plan of salvation after they had tried it, and renounced the only scheme of redemption after they had tasted its benefits. If that plan could not save them, what could? If they neglected that, by what other means could they be brought to God?
(3) This interpretation accords, as I suppose, with the exact meaning of the phrases which the apostle uses. An examination of those phrases will show that he refers to those who are sincere believers. The phrase "it is impossible" obviously and properly denotes absolute impossibility. It has been contended, by Storr and others, that it denotes only great difficulty. But the meaning which would at first strike all readers would be that "the thing could not be done;" that it was not merely very difficult, but absolutely impracticable. The word - adunaton (NT:102) - occurs only in the New Testament in the following places, in all which it denotes that the thing could not be done; Matt 19:26; Mark 10:27, "With men this is impossible;" that is, men could not save one who was rich, implying that the thing was wholly beyond human power. Luke 18:27, "The things which are impossible with men are possible with God" - referring to the same case; Acts 14:8, "A man of Lystra, impotent in his feet;" that is, who was wholly "unable" to walk; Rom 8:3, "For what the law could not do;" what was absolutely "impossible" for the Law to accomplish; that is, to save people; Heb 6:18, "In which it was impossible for God to lie;" Heb 10:4, "It is not possible for the blood of bulls and of goats to take away sin;" and Heb 11:6, "Without faith it is impossible to please God;" in all of these instances denoting absolute impossibility.
These passages show that it is not merely a great difficulty to which the apostle refers, but that he meant to say that the thing was wholly impracticable; that it could not be done. And if this be the meaning, then it proves that if those referred to should fall away, they could never be renewed. Their case was hopeless, and they must perish: that is, if a true Christian should apostatize, or fall from grace, "he never could be renewed again," and could not be saved. Paul did not teach that he might fall away and be renewed again as often as he pleased. He had other views of the grace of God than this; and he meant to teach, that if a man should once cast off true religion, his case was hopeless, and he must perish; and by this solemn consideration-the only one that would be effectual in such a case-he meant to guard them against the danger of apostasy.
[For those who were once enlightened] The phrase "to be enlightened" is one that is often used in the Scriptures, and may be applied either to one whose understanding has been enlightened to discern his duty, though he is not converted (compare the note on John 1:9); or more commonly to one who is truly converted; see the note on Eph 1:18. It does not of necessity refer to true Christians, though it cannot be denied that it more obviously suggests the idea that the heart is truly changed, and that it is more commonly used in that sense; compare Ps 19:8. Light, in the Scriptures, is the emblem of knowledge, holiness, and happiness, and there is no impropriety here in understanding it in accordance with the more decisive phrases which follow, as referring to true Christians.
[And have tasted] To "taste" of a thing means, according to the usage in the Scriptures, to "experience," or to "understand" it. The expression is derived from the fact that the "taste" is one of the means by which we ascertain the nature or quality of an object; compare Matt 16:28; John 8:51; Heb 2:9. The proper idea here is, that they had "experienced" the heavenly gift, or had learned its nature.
[The heavenly gift] The gift from heaven, or which pertains to heaven; compare the note on John 4:10. The expression properly means some favor or gift which has descended from heaven, and may refer to any of the benefits which God has conferred on man in the work of redemption. It might include the plan of salvation; the forgiveness of sins; the enlightening, renewing, and sanctifying influences of the Holy Spirit, or any one of the graces which that Spirit imparts. The use of the article, however - "the heavenly gift," limits it to something special, as being conferred directly from heaven, and the connection would seem to demand that we understand it of some "special" favor which could be conferred only on the children of God. It is an expression which "may" be applied to sincere Christians; it is at least doubtful whether it can with propriety be applied to any other.
[And were made partakers of the Holy Ghost] Partakers of the influences of the Holy Spirit-for it is only in this sense that we can partake of the Holy Spirit. We "partake" of food when we share it with others; we "partake" of pleasure when we enjoy it with others; we "partake" of spoils in war when they are divided between us and others. So we partake of the influences of the Holy Spirit when we share these influences conferred on his people. This is not language which can properly be applied to anyone but a true Christian; and though it is true that an unpardoned sinner may be enlightened and awakened by the Holy Spirit, yet the language used here is not such as would be likely to be employed to describe his state. It is too clearly expressive of those influences which renew and sanctify the soul. It is as elevated language as can be used to describe the joy of the Christian, and is undoubtedly used in that sense here. If it is not, it would be difficult to find any language which would properly express the condition of a renewed heart. Grotius, Bloomfield, and some others, understood this of the miraculous gifts of the Holy Spirit. But this is not necessary, and does not accord well with the general description here, which evidently pertains to the mass of those whom the apostle addressed.

Now, all I am saying is that you can grab a few (even several scriptures) and put together a doctrine, but you must always look at the entire context of the New Covenant. If you are saying that a person can lose their salvation, you are saying that Christ did not fully atone, that his blood/sacrifice was not totally pleasing to God, that salvation goes back to works and not grace, and so on. Remember, none can pluck us from the father's hand, the Holy Spirit has sealed us unto the day of redemption, Jesus became cursed for us, and we share in His righteousness, and so on. I hope this helps.
