If I Sin Willfully Have I Lost Salvation? - Hebrews  

People who believe that they can "lose their salvation" (sounds paradoxical to me) trust in their works, their own "righteousness" and have never gone through true repentance. This is said and written for them: ‭Matthew 7:21-23 [21] “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. [22] On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ [23] And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’ They don't even realise that. Strongly deluded!

​@alexandertrifonov8188 Those people in Matthew 7:22-23 believed in Jesus, did works Jesus told us to do but their belief was superficial, being devoid of repentance and they lived in continuous unrepentant sin which is iniquity. Jesus never knew them.

@@2Chronicles714_ Yes, so much for OSAS......

Here's some from Hebrews that show OSAS is a man-made teaching Hebrews 3:6-19 But Christ is faithful as the Son over God’s house. And we are his house, (IF) indeed we hold firmly to our confidence and the hope in which we glory.,7So as the Holy Spirit says: “Today, (IF) you hear his voice, 8do not harden your hearts as you did in the rebellion, during the time of testing in the wilderness, 9where your ancestors tested and tried me, though for forty years they saw what I did. 10That is why I was angry with that generation; I said, ‘Their hearts are always going astray, and they have not known my ways.’ 11So I declared on oath in my anger, [‘They shall never enter my rest.’ ”] 👉12 See to it brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God.👈 13But encourage one another daily, as long as it is called “Today,” so that none of you may be hardened by sin’s deceitfulness. 14We have come to share in Christ, (IF] indeed we hold our original conviction firmly TO THE VERY END. 15As has just been said: “Today, (IF) you hear his voice, do not harden your hearts as you did in the rebellion.” 16. Who were they who heard and rebelled? Were they not all those Moses led out of Egypt? 17 And with whom was he angry for forty years? Was it not with those who sinned, whose bodies perished in the wilderness? 18 And to whom did God swear that THEY WOULD NEVER ENTER HIS REST (IF) NOT TO THOSE WHO DISOBEYED? 19 So we see that THEY WERE NOT ABLE TO ENTER, BECAUSE OF THEIR UNBELIEF. [Note:disobedience is the equivalent to unbelief] Hebrews 4:1-11 1Therefore, since the promise of entering his rest still stands, let us be careful that none of you be found to have fallen short of it. 2For we also have had the good news proclaimed to us, just as they did; but the message they heard was of no value to them, because they did not share the faith of those who obeyed. a 3Now we who have believed enter that rest, just as God has said, “So I declare on oath in my anger, ‘They shall never enter my rest.’ ” And yet his works have been finished since the creation of the world. 4For somewhere he has spoken about the seventh day in these words: “On the seventh day God rested from all his works.” 5And again in the passage above he says, “They shall never enter my rest.” 6Therefore since it still remains for some to enter that rest, and since those who formerly had the good news proclaimed to them did not go in because of their disobedience, 7God again set a certain day, calling it “Today.” This he did when a long time later he spoke through David, as in the passage already quoted: “Today, if you hear his voice, do not harden your hearts.” 8For if Joshua had given them rest, God would not have spoken later about another day. 9There remains, then, a Sabbath-rest for the people of God; 10for anyone who enters God’s rest also rests from their works, e just as God did from his. 11Let us, therefore, make every effort to enter that rest, so that no one will perish by following their example of disobedience.

It starts with repenting of sin crucifying the flesh resulting in a change of conduct and becoming a new creation in Christ Jesus. Not sinless perfection but a pattern that aligns with God.

IF we are not Romans we should toss out Romans? IF we are not Corinthians we should toss out 1&2 Corinthians ? We are told not to add or take away from the word of God.

Yes the book of Hebrews is written primarily to Tribulation Jews who must endure till the end to be saved Matthew 24:13 KJV, Hebrews 3:14 KJV,Churge Age believers salvation is by faith alone and can never be lost ,it's eternal security,good works earn rewards at the Judgement Seat of Christ.

Beloved, If we're not Concerns with the Book of Hebrew, then, we're not concerns with all others books of the Holy Bible. GOD is GOD; HE can use anything to Illustrates HIS Thought!

okay, and why is that? Can you explain why? Thanks!

Once Saved Always Saved" (Eternal Security): Is It True? - Bob Wilkin ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UCstAS1QKMk.html Is "Once Saved Always Saved" (Eternal Security) True? Does the Bible Jesus teach "Once Saved Always Saved" (Eternal Security) Bob Wilkin of the Grace Evangelical Society demonstrates from the Bible why "Once Saved Always Saved" (Eternal Security) is true, since we have Jesus' word on it and Jesus never lies.

Roman's 11:29 clarifies the calling and gift's invitation of Salvation via the Cross even more than that his Ressurection proving that even death is mastered in Christ Jesus. Accept his calling and gift's invitation ask for help with the depraved condition and hopelessly lost. The calling and Great Awakening that inspires belief encourages the acceptance of Salvation by grace threw Faith alone in the finished works in Christ Jesus is sufficient for Salvation Everything needed for the Forgiveness past present and future sin of the sinful nature and it's desires also the serpents head was crushed and sin out of temptation schemes and Device's of the Devil Also addressed and complete in Christ Jesus his final sacrifice gave us approval, justification, sin debts erased and forgotten to those chosen to and fuelled by God to simply accept his calling and gift's.. Invitation to surrender and enter his rest. He initiates our salvation of good works he began Also promised he would finish it. Salvation by grace threw Faith alone in Christ Jesus repentance is not required nor is it ever revocable. Born again and the Great Awakening that occurs in the New Creation of Salvation. Isn't giving the gift back nor rejecting the Truth Namely Christ Jesus our Lord, Savior and one truth God. Jesus saves and lives there are those who are preaching and teaching yet deny the Truth or Power and authority in Christ Jesus to to accomplish salvation apart From human efforts and desires. Still considering themselves something when the Truth is Apart from grace and faith Jesus provides to believe In Christ Jesus. We are nothing. Practice this become clay more and more..Let the Potter do his thing ❤
