How do we know salvation is assured for believers?

The assurance of salvation for believers is rooted in the character and covenant of God. As Isaiah 26:1-2 illustrates, believers are invited into a strong city of refuge, symbolizing the security found in salvation appointed by God. Our salvation, confirmed by the work of Christ, stands on unshakeable foundations, emphasizing that it is not based on our uncertain righteousness but rather on Christ's perfect obedience and atoning sacrifice. This promise of salvation is not transient but reflects God's unwavering commitment to His elect, ensuring they are forever secure in His grace.
