A key component to faith is trusting in God in every circumstance, even when we don't understand. One way that has helped us grow our faith is reminding ourselves of all of the ways that God has been faithful to us. It helps us to combat our doubts because it shifts our perspective. Instead of focusing on the unknown, we focus on the nature of God - who He is and how He acts. And a key attribute of God is his faithfulness to us. He never has let us down nor will He ever because that is who He is.
