What does it mean to believe in your heart for salvation?

Believing in your heart goes beyond mere intellectual assent; it involves a heartfelt conviction that Jesus Christ is Lord and the Savior of your sins. Romans 10:10 elucidates that with the heart, man believes unto righteousness. This belief acknowledges one’s complete inability to achieve righteousness through their own works and relies solely on Christ's sufficient grace. It is an act of total surrender, where one's hope of salvation lies in the redemptive work of Christ alone, not in any human efforts or merit.
