How do we know that God's laws written in our hearts are true?

The assurance that God's laws written in our hearts are true rests on the conviction that there is a perfect harmony between our internal experiences and the external truth of Scripture. The Holy Spirit confirms in our hearts that we are indeed children of God, as stated in Romans 8:16. Our understanding of these laws is further deepened through experiences that reflect the teachings of Scripture, thus validating that the internal witness aligns with the written Word. This dual testimony serves as a source of comfort and guidance for believers, affirming the reality of salvation and the transformative work of God in their lives.
