What does the Bible say about God's laws written in our hearts?

The Bible teaches that God has promised, "I will put my laws into their mind, and write them in their hearts" (Hebrews 8:10). This prophetic declaration signifies that God's people are internally transformed and guided by His moral law, which is not merely an external set of rules but is inscribed on their hearts. This means that genuine obedience stems from a heart transformed by the Holy Spirit, leading to a profound personal knowledge of God and His ways, distinct from mere institutional qualifications.
