How do we know saving faith is true?

The truth of saving faith is evidenced by the transformation it brings in the believer’s life. Genuine faith is not merely intellectual agreement but results in a heartfelt response to the realities of sin and Christ’s suffering. This transformation manifests itself in sorrow for sin and a deep love for Christ, marked by a desire to mourn for what was done to Him. As Zechariah 12:10 illustrates, the true believer looks upon the crucified Christ and acknowledges the weight of their own transgressions, leading to a heartfelt lamentation.

Furthermore, the attributes of saving faith include both recognition of the gravity of sin and an understanding of God's grace. This acknowledgment creates a profound contrast between the believer’s past life and their new life in Christ, which serves as further evidence of the existence of a genuine saving faith. A heart touched by the reality of Christ's suffering is significantly changed, continually drawing the believer toward repentance and deeper devotion.
