How do we know the promise of salvation applies to us?

The promise of salvation is consistently declared in Romans 4:24, where Paul points out that 'it was not written for his sake alone' but for everyone who believes. This indicates that God's saving grace through Christ is not limited to a particular group but is available to all who place their faith in Him. However, the key is understanding that saving faith is divinely given; we do not initiate this belief on our own. As believers, we can confidently claim the promises of God because they are grounded in Christ's righteousness, not in our own actions or decisions.
