How do we know that salvation comes from God's will?

The doctrine of salvation through God's sovereign will is reaffirmed throughout Scripture. In John 6:39-40, Jesus states, 'This is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.' This underscores that salvation depends solely on God's decree, rather than human will or effort. Furthermore, the concept that eternal life is a gift from God is echoed in Romans 6:23, where the Apostle Paul writes that while the wages of sin is death, the gift of God is eternal life through Jesus Christ.
