I did answer. You either didn't like my answer or ignored it. And I was trying to save some time. I'm not really big on long posts. So while I do respect that you want to develop longer context, knowing the answer to my question allows me to know whether to bow out of the conversation or not.
You are free to answer or not, but my question to you is the very question Paul asks the Galatians...having begun in the Spirit, are ye now made perfect by the flesh?
And I'm fine with context. But if you don't understand purpose, you may not be understanding context.
So up to you...does Paul believe an individual is saved by grace but kept by personal endeavor?
OK, so you said it was a general exhortation. So, in your view general seems to include those "in Christ" which I assume you mean Christians.
I understood you quite well. And although it seems more than fair that Paul would not be assuming all in the Galatian Churches were in Christ, the reason I went through the exercise of showing from the Text who Paul is addressing, I think you're hard-pressed to find that his focus is not his fear - his concern for those
in Christ who are in danger of being deceived into
deserting to another/different gospel, turning again to bondage, seeing Paul as an enemy, desiring to be under law (vs. under grace), being entangled in bondage, having Christ be of no advantage to them, being estranged/released/set aside/discharged from Christ, fallen from grace, going from running well [in faith] to becoming disobedient to truth (which correlates to having no faith).
So, if you want to ignore all of this in favor of a theological model you favor, attempt to tell me I can't read Scripture in context, do not understand purpose so can't understand context, and you'd prefer to bow out, then please do.
Before you go, Paul does clearly believe an individual is saved by grace. Paul and the rest of the Text clearly present Biblical Salvation as a process that some identify as Justification > Sanctification > Glorification. Within this process, Paul clearly in fear warns those in Christ of the dangers of being deceived into deserting to another Gospel and falling from Grace and being released from Christ. There are several places that warn those in Christ about being deceived and command them not to be deceived. This becomes very circular because to disobey God's command is to be in a lack of faith and in this case to be deceived.
The rest of my answer will be to say that, yes, the Christian is involved in collaborating with God in this Salvation Process. And I'm happy to discuss all the active commands given to those in Christ to continue to believe, to abide, to endure, and so on, including to accomplish their salvation by work in collaboration with God who is providing the capabilities to both will and do what pleases Him.
It all just goes back to the foundational lesson Jesus gave to the woman at the well in John 4. God is Spirit and is seeking those who must and will bow in obeisance to Him in Spirit and in truth. This is quite simply a statement about the necessity to enter into and remain in faith obedience to Him as He teaches, commands and requires of those He gives to His Son. And it is these who the Son will raise in the last day. It is also these who truly love the Father, the Son and one another as Christ loved us and gave Himself for us.
It's only systematic theological models that make this difficult.
