Before Vatican II, some Catholics only came to Church every Sunday without fail because they were afraid of Hell. (The stick) Then when many priests and catechists stopped preaching and teaching about Hell, they just gradually stopped coming regularly. I think Jesus is sad because without fear of Hell, many don’t come to Mass just out of love for Him and His Body and Blood (The carrot.)
The reading today of Jesus with the Samaritan woman suggests that Jesus reminded her of the stick by mentioning her 5 husbands and her present lover, but then quickly lured her with the carrot by speaking of the eternal life He, the Messiah, wanted to bring to her.
Just as a mother watches her toddler, first fall every few steps, trying to walk, then gradually less and less, when I am teaching you through a spiritual director how to improve, I am not alarmed that you still make many, many mistakes. I just want you to hold My hand more and try again.
