My soul, wait thou only upon God; for my expectation is from him. He only is my rock and my salvation: he is my defence; I shall not be moved. In God is my salvation and my glory: the rock of my strength, and my refuge, is in God.
Psalm 62:5-7 (KJV)
When we place all our trust and expectation in the goodness and faithfulness of God, we will not be disappointed. While God often works through other people, let us remember always that He alone is the rock of our salvation and our strength.
