What does it mean that Jesus sees the heart?

When the sermon notes discuss Jesus' ability to see the heart, it emphasizes that God looks beyond outward appearances to the true condition of a person’s soul. This is illustrated by His display of compassion towards Levi, a tax collector considered a sinner by society. Jesus knew Levi’s heart and called him, revealing His search for those who need redemption. This is crucial because it highlights the biblical understanding that true repentance requires internal transformation rather than mere external conformity. God's insight into our motives compels us to acknowledge our need for grace and forgiveness, affirming the nature of His calling as both personal and transformative.
