It is sad that you are so determined to reject The FINAL Grace of God imputing the righteousness of Christ when you believe in whom God has sent for our salvation. You have learned to post passages you have been lead to believe support the works based catholicism you have joined to. The section in the letter to the Hebrews, reaching back into chapters four and five then stepping into chapter six could actually help you to understand the finality of salvation when you believe ... if you were open to learn, which you show you are not.
Growing in grace and knowledge is work. It is the sanctification process not the justification moment. There are going to be a lot of very surprised Catholics in the instant transformation from this 4D realm to the hyper-dimensional realm at the rapture. I hope you are among them
A very nice Catholic understanding of Salvation. Reflect on it.
The quote from Hebrews makes clear the presumption of “irrevocably” is false.
