I believe until we grasp God's infinite attention and care for the small things, we won't really appreciate how much God cares for us. If God cares that much for the fifth sparrow, how much more does he care for you and me. See, if we don't learn to share God's attitudes, we won't understand God's attitude toward us as His children. Show people you care by listening to them.
Matthew 10:29-30 (NIV)
29 Are not two sparrows sold for a penny? Yet not one of them will fall to the ground apart from the will of your Father.
30 And even the very hairs of your head are all numbered.
