How does conscience relate to knowledge of God?

In Romans 2:14-15, Paul explains that even those who don't possess the Law of Moses still instinctively know the moral law of God through their conscience. This internal witness serves as a means by which God has made His truth known to all people. Though they may not have direct revelation, humanity is aware of God's moral expectations and stands accountable. This suggests that conscience is part of the common grace given to all, pointing towards an inherent understanding of right and wrong, reflecting God's law.
