How do we know salvation is of God?

Salvation is a divine gift, not something attained by human merit or works. This is clear in John 1:11-13, where it states that those who are saved are 'born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.' This indicates that our regeneration and the new birth are solely orchestrated by God's will and grace. Jonah proclaimed, 'Salvation is of the Lord' (Jonah 2:9), underscoring that no one can boast about their salvific standing before God. Furthermore, in Galatians 2:16, it is highlighted that a person is justified by faith in Jesus Christ, not by works. Believers are justified based on Christ’s righteousness, not their own efforts, which further affirms that salvation rests entirely in God's hands.
