How does God's immutability relate to salvation?

God’s immutability, the doctrine that He does not change, is foundational to understanding the security of salvation. In James 1:17, it states that with God, there is no variableness or shadow of turning. This implies that His promises, including the promise of salvation through Jesus Christ, are reliable and eternal. Unlike human beings who might change their minds or intentions, God remains faithful to His plans and purposes. This provides believers with the assurance that their salvation is secure in Christ, as Hebrews 13:8 declares that Jesus Christ is the same yesterday, today, and forever, reinforcing the truth that God’s gifts are irrevocable.
