Correct Option: A. He had compassion on his son Detailed Explanation: The parable of the Prodigal Son, found in Luke 15:11-32, is a powerful story that illustrates themes of forgiveness, redemption, and unconditional love. In this parable, the father represents God, and the son represents humanity, particularly those who stray away from the right path.

1. Compassion as a Central Theme:
2. The father’s reaction upon seeing his son returning home is one of deep compassion. The text describes how he ran to his son, embraced him, and kissed him. This immediate and loving response highlights the father's emotional state—he is filled with compassion, which is the driving force behind his actions.
3. Compassion is a fundamental aspect of the Christian faith, reflecting God's love for humanity. The father's willingness to forgive and accept his son back without hesitation demonstrates the nature of divine love and mercy.
4. The Role of Confession:
5. While option B states that the son confessed his sins, which is indeed an important part of the story, it is not the primary reason for the father's welcoming embrace. The father’s compassion precedes the son’s confession. The father’s love is unconditional, and he does not wait for the son to express remorse before he acts.
6. The confession is significant as it shows the son’s recognition of his mistakes, but it is the father’s compassion that prompts the welcoming response.
7. Missing His Son:
8. Option C suggests that the father welcomed his son back because he had missed him for a long time. While it is likely true that the father missed his son, this option does not capture the essence of the father's actions. The father's compassion is a more profound and immediate reason for his response than merely missing his son.
9. The emotional depth of the father's love is not solely based on absence but on a deep-seated desire for reconciliation and restoration.
10. Wondering About His Son’s Condition:
11. Option D states that the father welcomed his son back because he wondered how wretched his son had become. This option implies a sense of judgment or concern about the son’s state, which does not align with the father’s immediate reaction. The father does not express disappointment or judgment; instead, he focuses on the joy of reunion.
12. The father's compassion is not contingent upon the son’s condition but is an expression of love that transcends the son’s past actions.

Summary of Key Points:

• The father’s compassion is the primary reason for welcoming the son back, reflecting God’s unconditional love.
• The son’s confession is important but secondary to the father’s initial response of love and acceptance.
• Missing his son (Option C) and wondering about his condition (Option D) do not capture the essence of the father’s actions as effectively as compassion does.
• The parable emphasizes themes of forgiveness, redemption, and the joy of reconciliation.

Revision Summary:

• The father’s compassion is the key reason for his welcoming response.
• The son’s confession is significant but not the primary motivator for the father’s actions.
• The story illustrates God’s unconditional love and forgiveness.
• Understanding the emotional depth of the father’s love is crucial for interpreting the parable correctly.
