Works of Mercy (1970)

Levi, a devout member of his church's youth group, yearns for the respect and recognition of his minister. Yet at every turn he is outshone by a fellow member of his youth group, a girl for whom winning new converts comes easy. Anxious to prove himself during the church’s meals-on-wheels program, he presses a lonely woman with a sickly father to accept one of their spare meals—in hopes of signing up the pair for the youth group’s route and bringing their names back to his minister. The woman is charmed by his insistence, and invites Levi in to feed her deteriorating father... but inside her apartment, Levi quickly finds himself confronted with a side of life his minister's teachings haven't prepared him for.
