What does it mean to have a clean heart?

In Psalm 51, David’s plea for a 'clean heart' signifies a deep desire for spiritual restoration and purity after recognizing his transgressions. A clean heart is one that is regenerated by the Holy Spirit, free from guilt, sin, and the shame that distances us from God. This is the promise of the new covenant, where God enables His people to walk in His ways and experience the joy of salvation. It involves a continuous relationship with Christ, relying on His blood to cleanse and renew, leading to a life that glorifies God and enjoys Him forever.
