How do we know God's grace is necessary for salvation?

The necessity of God's grace for salvation is established through Scripture, which repeatedly emphasizes that human beings, in their natural state, are unable to seek God or come to Christ unless divinely enabled. John 6:65 explicitly states that no one can come to Jesus unless it has been given by the Father. This implies that our capability to believe or accept Christ originates from God's grace rather than human effort.

Furthermore, this aligns with the Reformed understanding of total depravity, which teaches that fallen humanity is incapable of achieving salvation on its own due to spiritual deadness. Thus, God’s grace is not merely an aid but an essential component for salvation, as it is the means by which individuals are transformed and brought to faith in Christ. Without this sovereign grace, all would remain in their trespasses and sins, devoid of the ability to respond to spiritual truths.
