Why is sinning against knowledge considered worse?

In the sermon, it's emphasized that David’s sin of numbering the people was particularly grievous because he acted against the light of God's direct revelation. When believers are aware of God's will and choose to disregard it, this constitutes a presumptuous sin. The gravity of such rebellion lies in the willfulness behind it. This idea resonates with the biblical principle that greater knowledge brings greater accountability. The implications serve as a stern reminder for Christians to heed the warnings of Scripture and to recognize the serious nature of betrayal against divine truth.
