How do we know salvation is a heart work?

Salvation is fundamentally a work of the heart, as noted in the sermon where it emphasizes that true worship begins with love for Christ. It’s not merely adherence to doctrines but a genuine relationship where one's heart overflows with love for Him. This concept is reinforced by the idea that 'out of the abundance of the heart, the mouth speaks' (Matthew 12:34), indicating that true transformation originates in one's affections and devotion to Christ. Therefore, understanding salvation as a heart work necessitates recognizing that it involves a personal, heartfelt connection with the Redeemer.
