Give me the only ones in context that support losing your salvation.
I believe they all do, although those that would refuse to believe might argue context even when it is obvious. I am not accusing you of being in that camp. Since you asked, I will give you a few examples:
The word abide in scripture means to “remain.” In John’s letters this theme is repeated numerous times. This is an example.
1 John 2: 24-25
Let what you heard from the beginning abide in you. **If **what you heard from the beginning
abides in you,
then you will
abide in the Son and in the Father. And this is what he has promised us,
eternal life.
James 5: 19-20
My brethren, if any one among you wanders from the truth and some one brings him back, let him know that whoever brings back a sinner from the error of his way will save his[the sinner’s] soul from death and will cover a multitude of sins.
This verse from James clearly shows how someone can wander from the truth or fall away through sin. They can, however, be restored. Once saved always saved? No way.
2 Peter 1: 10-11
Therefore, brethren, be the more zealous to** confirm your call and election**, for **if **you do this you will never fall; so there will be richly provided for you an entrance into the eternal kingdom of our Lord and Savior Jesus Christ.
Notice that Peter says that the believers need to confirm their call and election so that they will not fall and will thus have an entrance into heaven. There is clearly a provisional nature to our salvation while we still struggle in this life.
2 Peter 2: 20-22
For if, after they have escaped the defilements of the world through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overpowered, the last state has become worse for them than the first. For it would have been better for them never to have known the way of righteousness than after knowing it to turn back from the holy commandment delivered to them. It has happened to them according to the true proverb, The dog turns back to his own vomit, and the sow is washed only to wallow in the mire.
Notice how Peter makes it clear that believers are even worse off should they fall and turn away from what they had received than if they had never known our Lord and Savior.
Romans 11: 20-21
That is true. They were broken off because of their unbelief, but you stand fast only through faith. So do not become proud, but stand in awe. For if God did not spare the natural branches, neither will he spare you. Note then the kindness and the severity of God: severity toward those who have fallen, but God’s kindness to you, **provided you continue **in his kindness; otherwise you too will be cut off.
Paul uses the word “provided.” This is again a message of the provisional nature of our salvation. We too can be “cut off.”
Hebrews 6: 4-8
For it is impossible to restore again to repentance those who have once been enlightened, who have tasted the heavenly gift, and have become partakers of the Holy Spirit, and have tasted the goodness of the word of God and the powers of the age to come, if they then commit apostasy, since they crucify the Son of God on their own account and hold him up to contempt. For land which has drunk the rain that often falls upon it, and brings forth vegetation useful to those for whose sake it is cultivated, receives a blessing from God. But if it bears thorns and thistles, it is worthless and near to being cursed; its end is to be burned.
Nothing could be more clear than this passage from Hebrews. A believer that apostacizes is done for. Their end is to be burned.
I hope these examples meet your need for context.
