Speculation will avail you nothing. Since you invoked this text as proof or in support of purgatory you need to show that those suffering stripes were saved, which is not said but all are classed as unfaithful unprepared sinners, and that these souls where in in purgatory awaiting entrance into Heaven, yet the only location that is mentioned is that of with the lost, and the only experience mentioned is that of suffering.
And you need to show that this postmortem suffering was due to sins for which they has not been punished enough for while on earth, while others did so while still on earth (according to purgatorial doctrine), but instead there are no exceptions in the warnings, even inferred, and all the unfaithful, unprepared souls will be punished.
In short, what you need to show in order for this to support purgatory and overcome alternative explanations is what cannot be shown. Again, give it up, as your attempts are an argument against purgatory being Scriptural.
Taking the text as it is, nothing added, nothing taken away, there is no use of the word saved here. There is mention of the kingdom and it is the Father's good pleasure to give the kingdom to the little flock to whom the Messiah was speaking. He told them what to do. Sell that which you have and give alms. Be ready and waiting for the Lord can come for you at any hour, and at an hour you think not.
The preceding parable of the rich man, who was not focused on watching and waiting and did not know the hour of the night that his soul would be required of him, leads right into the rest of the lesson. The lesson is given in terms of servants; they are all servants of the LORD. The instruction could be summarized in symmetry with the admonition of the Apostle Paul to present your bodies as a living sacrifice, holy, compassionate to the poor, resisting temptation and sin, and always waiting on the LORD, night and day, until you are called to account for your service.
And you need to show that this postmortem suffering was due to sins for which they has not been punished enough for while on earth, while others did so while still on earth (according to purgatorial doctrine), but instead there are no exceptions in the warnings, even inferred, and all the unfaithful, unprepared souls will be punished.
In short, what you need to show in order for this to support purgatory and overcome alternative explanations is what cannot be shown. Again, give it up, as your attempts are an argument against purgatory being Scriptural.
All I need to do is believe and obey everything the Messiah said to the best of my understanding. Love the LORD with all my heart, soul, and strength; love my neighbor as myself.
