I fear you do not understand what it will mean for the world to experience a direct and unveiled encounter with the unavoidable Truth, how unbearable it will be for those not conformed to Christ, to be in his presence. That is why we call it judgment.
Who may abide the day of his coming? and who shall stand when he appeareth?
Everything and everyone failing to give glory by signifying him will flee him, because his very presence will be an unavoidable, unendurable judgment. Those who did nothing more than cry Lord, Lord while refusing to conform themselves in his image, will not be saved.
You asserted, quite sincerely, apparently< "Those who did nothing more than cry Lord, Lord while refusing to conform themselves in his image, will not be saved." You do err in that you presume you can conform yourself to His Character. You do also err n not believing you can be saved NOW, right this minute, and have God's eternal life placed in you, just as the believers on Pentecost and the believers in the House of Cornelius had that eternal life put into them, immediately on believing in The Savior as Their Redeemer.
Only God in you can accomplish that, by the submission of your will. You can strive or work or follow the sacrament trail, whatever you want to call it as Catholicism teaches the perishing to do, but you will accomplish not one farthing toward your redemption by your efforts trying to be like Him.
ONLY His life in you can do that new life , for it is God Who is in you to will and to do of His good pleasure. When one is born from above, He puts His eternal life in them and then raises them up in the way that they should go.
I realize that is incomprehensible for a catholic who has been indoctrinated to strive for eternal life, but there it is for you to accept or reject.
