The idea that Jewish and Christian theologians interpret Noah's faith differently is a new idea for me. Seeing Noah as "reluctant" just because he was the last one in seems a stretch after all he had done and gone through just to get the ark built to begin with.
Another item they didn't mention and a lot of folks don't know is that Noah brought 7 of every clean animal into the ark in order to have food and sacrifices during the year they were locked in. It's also amazing to discover how big that ark really was. I won't tell you, I'll let you ferret that out on the Internet.
