Jesus wants pure hearts, not better behavior. And only Jesus can change our heart to make it pure. It is not enough to merely do the right things externally; we can do good things for the wrong reasons. Jesus is concerned that our thoughts, motives, and emotions behind our choices and actions align with His heart and character. He longs to give us a new heart and to put a new spirit in us. Jesus desires to give us a pure heart if we will cry out to Him and confess our need for His help, that we are powerless to change our own hearts.
