How do we know that faith in Jesus leads to salvation?

The assurance of salvation through faith in Jesus is rooted in several biblical passages. Ephesians 2:8-9 articulates that 'For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.' This underscores that salvation is not earned through personal efforts but is a gracious gift from God that can only be received through faith. Furthermore, John 6:37-40 provides confidence that everyone the Father gives to Jesus will come to Him, and He will not cast them out. Jesus' work is comprehensive and ensures that those who believe in Him will be raised on the last day. Therefore, the power and efficacy of faith stem from its object, who is Christ Himself.
