How do we know that salvation by faith is true?

Ephesians 2:8-9 clarifies that 'by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.' This passage underscores that salvation is not based on human effort or merit but on the grace of God, which grants faith to the elect. The faith that saves is a divinely provided gift that allows believers to trust wholly in the work of Jesus Christ for their redemption. Historical confessions of the Reformed faith uphold this truth, confirming that it is through faith alone, as emphasized in the Five Solas, that we receive salvation.
