JMHO, but simply saying that showing his faith while being crucified himself was a work. And frankly, given the circumstances, a pretty big one.
A work??? How in the world did you ever come up with that??? Of course it was not a work...Works for Salvation will get you straight into Hell...
THIS is what he did...
Rom 10:13 For whosoever shall call upon the name of the Lord shall be saved.
He acknowledged that the guy on the 3rd Cross was God...He aknowledged that THAT God could save hime...He acknlowedged himself to be a sinner in need of saving...And he called on the Lord to save him...
That's the biblical plan of Salvation...
And then Jesus died...Jesus then went to Hell...To Hell to the Compartment of Abraham's Bosom...Jesus preached to the Saints in Hell...
Jesus then unlocked the Gates of Hell so that Hell would not prevail over His church (for those of you who think that the gates of Hell are something other than the gates of Hell)...Now you finally know...
AMEN, Iscool. Why is that so hard to understand?
