Did Sara Tucholsky hit a home run?
Yes.
Did she have everything she needed to score?
Not after she injured her leg.
She couldn’t make it around the bases.
How was Sara just like a poor soul in purgatory?
She earned the right to score after she hit a home run. Similarly, the souls in purgatory have been judged favorably by God and given the right to go to heaven some day.
However, Sara couldn’t help herself get home. Just like the poor souls, she needed others to help her reach her destination, home.
