What do Reformed Christians believe about free will?

Within Reformed theology, the concept of free will is viewed in light of human incapacity to choose God apart from divine intervention. Romans 9:16 asserts that salvation depends not on human will or effort but on God's mercy. This indicates that our salvation was predestined by God and is entirely a result of His sovereign grace. The idea of free will, in light of sin, suggests that while humans make choices, those choices are influenced and ultimately governed by God's sovereign plan, affirming that He alone is the author of salvation.
