Why do Reformed Christians reject free will?

Reformed Christians argue that the notion of human free will, especially in matters of salvation, undermines the sovereignty of God. The Bible teaches that humans, in their natural state, cannot choose God due to their fallen nature, as expressed in Ephesians 2:1, which describes humanity as 'dead in trespasses and sins.' This dead state implies total inability, necessitating God's intervention through regeneration. Furthermore, John 6:44 states that 'No one can come to Me unless the Father who sent Me draws him,' indicating that salvation is a result of God’s sovereign action rather than human choice. Consequently, the emphasis is placed on God's grace as the decisive factor in redemption, as humans are inherently inclined to sin without divine initiative.
