What does it mean to be pure in heart?
Is my heart pure? That is an essential issue to address. Jesus lays it out in His manifesto (Matthew 5 — 7).
Am we clean, blameless, unstained from guilt? Not on our own but we have been declared innocent because of the work of Jesus and we are being sanctified by His refining fire and His pruning.
Now that is some good news! Jesus gives us clean hands. Jesus gives us a pure heart. Jesus promises we will see God.
