How do we know that faith in Jesus brings joy?

Believing in Jesus fosters a unique relationship that produces an internal joy, as indicated in 1 Peter 1:8-9. This joy arises from the believer's understanding of who Christ is and what He has accomplished in redemption. As the believer contemplates Jesus's character and sacrificial work, it leads to an experiential faith that results in a joy that surpasses earthly happiness. The assurance of salvation further enhances this joy, fulfilling the believer's hearts with peace and gratitude.
