Today, you may be the only reason someone investigates to words of Jesus.
Today, you might break the cycle of what someone thought they knew about Jesus, and they will seek Him.
Today, you might make someone realize that all of their fears, and negative preconceptions of Christians... are true.
Today, you may show someone absolutely nothing.
Today, you may do this without ever knowing that you did.
You can help build up, or destroy someone's spiritual and eternal worldview today.
For those who say that Christ is their Lord and Savior, always remember that someone is watching you, and could be shaping their vision of faith upon your actions and words.
