Jesus told us not to be afraid. We are worth more than many sparrows, and God is aware of each one, none of which dies without His permission. Why, God even knows how many hairs are on our heads! Quite amazing, even if we are practically bald. Why would God care about such inconsequential (to our minds) things such as sparrows and heads of hair? Because God is Father to all and good fathers care. These words of God should be comforting to us because they show us how valuable we are in God's eyes. So we ought to value ourselves and others.
