Genesis 15:5:  “He [God] took him [Abraham] outside and said, ‘Look up at the heavens and count the stars–if indeed you can count them.  Then he said to him, “So shall your offspring be.”

Two messages here:  1)  Look up to the stars and the heavens and take in God’s amazing wonders and love of beauty.  2)  Believe God when He promises you something.  Cast all doubts aside and believe!
