Here are some scriptures that would suggest we can lose salvation... would love your thoughts as well as anyone else's
Matthew 6:15
But if you do not forgive others their sins, your Father will not forgive your sins.
Luke 12:41-46
Peter asked, Lord, are you telling this parable to us, or to everyone? The Lord answered, Who then is the faithful and wise manager, whom the master puts in charge of his servants to give them their food allowance at the proper time? It will be good for that servant whom the master finds doing so when he returns. Truly I tell you, he will put him in charge of all his possessions. But suppose the servant says to himself, My master is taking a long time in coming, and he then begins to beat the other servants, both men and women, and to eat and drink and get drunk. The master of that servant will come on a day when he does not expect him and at an hour he is not aware of. He will cut him to pieces and assign him a place with the unbelievers.
1 Corinthians 15:1-2
Now, brothers and sisters, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
Colossians 1:22-23
But now he has reconciled you by Christs physical body through death to present you holy in his sight, without blemish and free from accusationif you continue in your faith, established and firm, and do not move from the hope held out in the gospel. This is the gospel that you heard and that has been proclaimed to every creature under heaven, and of which I, Paul, have become a servant.
Hebrews 3:6
But Christ is faithful as the Son over Gods house. And we are his house, if indeed we hold firmly to our confidence and the hope in which we glory.
Hebrews 3:14
We have come to share in Christ, if indeed we hold our original conviction firmly to the very end.
2 Peter 2:20-22
If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and are overcome, they are worse off at the end than they were at the beginning. It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them. Of them the proverbs are true: A dog returns to its vomit, and, A sow that is washed returns to her wallowing in the mud.
