Genuine faith in Christ is evidenced by a transformed life and a heartfelt desire to know Him more deeply.
The assurance of genuine faith lies in the transformation it produces in a believer's life. As indicated in Philippians 3:10, the believer's longing to know Christ and commune with Him demonstrates the work of the Holy Spirit in their heart. If all earthly pursuits seem worthless compared to knowing Him, it indicates the authenticity of one's faith. The joy and satisfaction found in Christ alone reflect a true engagement with His grace and power, confirming the security of that faith as articulated in 2 Timothy 1:12, where Paul states he knows whom he has believed.
