When Edward says that sinners are “hang by a slender thread" he means that every sinner will have to pay for his sinful act and no one can be saved from the God's fury.
Explanation:
‘Hang by a slender thread’ is a line from the sermon ‘Sinners in the Hands of an Angry God’ which is authored by Jonathan Edwards. The sermon focuses on the Great Awakening and it depicts that there is indeed a place like hell.
When Edward said ‘hang by a slender thread’ he meant that sinners are being held by thread over hell and the fury of God will cause them to fall. He states that there’s nothing that can protect sinners from the anger of God.
