Sinners in the Hands of an Angry God is one of Johnathan Edwards' most well-known sermons. It seeks to stir humanity to realize the dangers that most assuredly await their immortal souls.
The four choices that are given as answers to your question are fear, logic, laws and hopes of reward.
If you were to pick logic as your answer, that only applies if you have a fear of the outcome if you choose to continue to reject Christ as your Savior.
Should you choose to follow the laws of God, it is because you fear the damnation of your immortal soul.
Your hopes of a reward from God, that of sparing your soul the torments of hell, are based upon your fear of those torments.
Fear of the logical outcome of ignoring God's laws and losing one's reward would be what prompts you to seek the comfort of claiming the absolution provided to you by claiming the peace provided to you when you incorporate the belief and acceptance of Christ for your spirit's salvation from God's wrath.
