You can be secure in Jesus. You don't have to wonder if you are good enough or if you can maintain a certain amount of works. You don't have to wonder if you will go to purgatory or worry that the Pope or some other tall hat will pronounce you unfit. You don't have to worry about God taking away the gift of faith. It was never your faith in the first place, you never earned it, and it is secure.
Did Judas lose his salvation or is he in heaven?
"You can be secure in Jesus"
Yes. Paul says nothing can keep us from the love of God and we can trust Jesus' promise. However, Scripture clearly tells us that WE can fall away from Christ. If we do not return, as the Prodigal son, we damn ourselves.
Btw, Purgatory is for the saved, and only God Himself can declare someone "fit" for heaven. Church teaching is that no one specific is in Hell. We don't know Hitler's faith in Christ before he died. (odds good he is not among the saved). God doesn't take away our gift. We give it up. Again, the prodigal son walked away on his own, he was not kicked out.

Read BONDAGE OF THE WILL by Martin Luther..(xviii)Of the comfort of knowing that salvation does not depend on free-will.
"If I lived and worked to all eternity my consience would never reach comfortable certainty as to how much it must do to satisfy God. What ever work I had done, there would still be a nagging doubt as to whether it pleased God, or whether He required something more."
