Hagar was mistreated and rejected. As a slave, she also had very few rights. When she runs away from her mistress God meets with her. Hagar calls Him the God who sees me (v13) and she continues to have faith in Him. God sees you. God knows you by name. God knows how many hairs there are on your head and He knows you.
Go to God with your worries, go to Him with your pain and your hard times or your happy times. God. Sees. You.
