Are Faith and Repentance Themselves 'Works' by Which We Are Justified?

Edwards, jotting down private ruminations in a personal notebook--

Faith is the condition of salvation because it trusts in Christ and ascribes salvation to him. Repentance is the condition because it renounces confidence in self and disclaims the glory of salvation. So neither of them justifies as a work, for the nature of the one is to renounce works, and the nature of the other is to depend on the works of another.
