Answer: Believing in the power of God's to save us from eternal destruction.
Puritan sermons often focused on the power of God to save humans from eternal destruction. The sermons emphasized the importance of believing in this saving power. The sermon "Sinners in the Hands of an Angry God" by Jonathan Edwards, is a good example of this. This sermon argues that following doctrines is not the way to achieve salvation. The only way to reach it is to put oneself on the hands of God, and to believe in his power to grant us eternal salvation.
