Renew:  it means to restore, to increase the life, to regenerate, to revive, to make like new.  Like those who take an old piece of wore out furniture and refurbish it to give it new life.  Or the person that can take an old beat up car and turn it into a rebuilt thing of beauty.  Then there is the craftsman that can take weathered reclaimed wood and build something that looks amazing.  God has the power and ability to 'RENEW' your life and turn it into something beautiful.
