This psalm teaches us of God's vastness. How He can use our weaknesses to show His strength. This Psalm also teaches His love for us, when we consider all His creation, yet He knows everything about us, even down to the number of hairs on our head. It shows us Christ's humility, to come down from heaven and become a man, so we could experience God's love. Finally, our responsibilities are to take care of this beautiful creation, the earth, and all that is in it.
