How do we know God's sovereignty in purification is true?

The sovereignty of God in our purification is fundamental to understanding His grace. Scriptures such as Isaiah 14:24 affirm that what God wills is accomplished. In Luke 5, the leper acknowledges Christ's power, saying, 'If You will, You can make me clean.' This indicates that God's will is the operative force behind our cleansing. The New Testament furthers this by teaching that God purifies our hearts through faith, establishing that our purification is fundamentally rooted in His sovereign choice and action, not in our abilities or works.
