Why is it important to have a new heart to worship God?

In Ezekiel, God promises to give His people a new heart, one that can engage in true worship. The old heart is unresponsive and incapable of praising God as He deserves. This new heart is capable of heartfelt worship, which is the essence of true worship in spirit and truth. When we worship from this new heart, we glorify God authentically and reflect our understanding of His holiness, grace, and goodness. A transformed heart leads to a transformed life, characterized by praise and gladness regardless of circumstances.
