How do we know the teachings of Andrew Fuller are false?

The teachings of Andrew Fuller are deemed false because they introduce dualism that undermines the sovereign grace of God in salvation. Fuller's concept suggests that both God and man are sovereign partners in salvation, implying that God's will can be resisted. This contradicts the clear biblical revelation that God alone carries out the work of redemption without dependence on man's cooperation. Furthermore, Fuller's adoption of universal atonement creates confusion about the efficacy of Christ's sacrifice, fundamentally contradicting the teachings established at the Synod of Dordrecht. His notions regarding 'duty faith' also mislead believers into thinking they possess the inherent ability to respond to the Gospel without the need for the Holy Spirit's transformative work. Thus, Fuller's theology lacks the saving power found in the pure Gospel of grace.
