Final answer:
Annette's reluctance to ask Jesus into her heart is ironic given that her principles of love and justice align with Christian teachings, despite her disillusionment with her churchmen and religion.
Step-by-step explanation:
The irony in Annette's hesitation to ask Jesus into her heart arises from the contrast between her spiritual beliefs and her disillusionment with the religious figures and practices surrounding her.
Although she has a strong sense of morality and justice founded on the principle of love, her doubts about her soul, churchmen, and religion reflect a deep conflict. The divine command to love your enemies is the cornerstone of her faith, untainted by the human failings of her religious community.
