How do we know that God does not need our cooperation for salvation?

The claim that God needs human cooperation for salvation betrays a misunderstanding of His sovereignty. The Bible presents a different picture; for instance, in Acts 13:48, it is stated, 'As many as were ordained to eternal life believed.' This suggests that belief is a result of God's ordaining, not an act of human initiative. Moreover, the transformation of the heart is also a divine act, as Ezekiel 36:26 tells us that God must give us a new heart and a right spirit. In light of these scriptural assertions, it is clear that God's saving grace operates without dependence on human effort or decision, thereby affirming His power and authority over salvation.
