And here we have an irreconcilable difference because I aver that if anyone - anyone - ever was good enough ("works") to get into heaven then Christ died for nothing.

This does not follow. Christ died so that your works may have the fruit of salvation. Without Him, they would be dead, see Romans 3-5. With Him, they brign you to the finish line:
24 Know you not that they that run in the race, all run indeed, but one receiveth the prize? So run that you may obtain. 25 And every one that striveth for the mastery, refraineth himself from all things: and they indeed that they may receive a corruptible crown; but we an incorruptible one. 26 I therefore so run, not as at an uncertainty: I so fight, not as one beating the air: 27 But I chastise my body, and bring it into subjection: lest perhaps, when I have preached to others, I myself should become a castaway.(1 Corinthians 9)
