A would-be disciple, who puts his hand to the plough and looks back lacks

Explanation

This question is asking about what a would-be disciple lacks if they put their hand to the plough and look back. The phrase putting your hand to the plough refers to making a commitment to follow Jesus. In this context, looking back means going back to one's old ways or being distracted from following Jesus.

Option A suggests that the would-be disciple lacks faith, but this is not the correct answer. Faith is important for following Jesus, but the question is asking specifically about what is lacking when someone puts their hand to the plough and looks back.

Option B suggests that the would-be disciple lacks kindness, but this is also not the correct answer. While kindness is an important value in Christianity, it is not directly related to the scenario described in the question.

Option C suggests that the would-be disciple lacks repentance, but this is not the correct answer either. Repentance is important for turning away from sin and turning towards God, but it is not directly related to the scenario described in the question.

Option D correctly states that the would-be disciple lacks total commitment. When someone puts their hand to the plough and looks back, they are not fully committed to following Jesus. Total commitment is necessary for being a true disciple of Jesus.

In summary, the correct answer to this question is Option D: Total commitment. This means that a would-be disciple who puts their hand to the plough and looks back lacks total commitment to following Jesus. To learn more about this, please read the relevant sections of the recommended textbooks.
