Hi Sufjon, We as Catholic’s never take it upon ourself to judge ourself. Do you understand what I am saying.
God is who judges us, So for us to say we know who we are is like saying we are equal to God. Only God will reveal to us at the end of our life what we are and what our fate is.
St Paul said this the best. St Paul as you know turned away from his sin and repented and became a Apostle of God. He spent the rest of his life working for God and God only. But here is his take on Salvation.
Here is one scripture. 2 Cor:15 And his heart goes out to you all the more as he remembers the obedience of all of you, when you received him with fear and trembling.
That is how we are told to work our our Salvation. We do not have the mind of God nor ever will. So we pray that he will accept us, but he is the final judge.
Jesus tells us many will say at the end did I not speak in your name, and He will said I do not know you. Many people do things for themself no God and God knows who they are.
Just thought I would throw that in

Have a good week-end!
