How does God provide assurance of salvation?

God provides assurance of salvation to His people in multiple ways, primarily through His promises and the internal testimony of the Holy Spirit. Isaiah 35:10 states that the redeemed will return to Zion with joy, highlighting God's faithfulness to His covenants. The Spirit also works within believers, testifying to their spirit that they are children of God (Romans 8:16). Through regeneration and the resulting fruit of faith and repentance, believers receive the assurance that they are secure in Christ, who protects them now and forever.
