Why is it important that salvation is a work of God?

The importance of salvation being God’s work lies in the assurance it provides to believers. If salvation were contingent upon human actions, it would lead to insecurity and fear of failure. As noted in Philippians 1:6, 'He which hath begun a good work in you will perform it until the day of Jesus Christ,' we see that God not only initiates but also sustains and completes the work of salvation. This divine guarantee allows believers to rest in the truth that their salvation is anchored in God's unchanging purpose and love, liberating them from the anxiety of trying to earn or maintain their standing before Him.
