Answer:
D. To scare people who might identify themselves as sinners to realign themselves with God.
Step-by-step explanation:
Jonathan Edward's famous sermon "Sinners in the Hands of an Angry God" uses powerful and strong language to try to persuade the people to turn from their evil ways. He implores on the people to repent and seek salvation/forgiveness before the world ends.
Edwards uses some harsh words, some powerful, strong language and at times even some scary words to depict the future of a man if he keeps living his current sinful life. He paints a picture of God as someone who is 'vengeful, hurt and angry' over his people's sinful nature. Giving a vivid description of the fate of anyone ignoring his warning about the wrath of God, he tried to persuade them to give up their wrongdoings and lean towards the Lord.
Thus, the correct answer for the overall purpose of the speaker in the sermon is to scare people who might identify themselves as sinners to realign themselves with God.
