Salvation doesn't imply we will never sin again.
The landmark is merely the baptism of the spirit.
It is only nauseating for somebody who believes they can discern and judge who is saved and who isn't. Only God knows our heart.
Only God knows who is saved and therefore who will sit next to him in the next life. No human knows.
Proclaiming it out loud is the heighth of arrogance; pride comes before the fall.
