If you read Hebrews 11, you'll notice faith is continually identified in terms of the actions a person takes, rather than the feelings they are experiencing.
Noah constructed an ark for the saving of his household. (vs. 7)
Abraham went out, not know where he was going. (vs. 8)
Isaac invoked future blessings. (vs. 20)
Rahab had given a friendly welcome to the spies. (vs. 31)
Does a Christian exhibit their faith through their actions? Or is it by our actions that we strengthen the faith already within us? Whether our actions go boldly before our faith, or trail supportively behind it, we soon discover that at some point they must go hand in hand. We stubbornly express our faith by our actions (works), and in doing so show that actions and faith cannot be separated.
James 2:26 tells us that to declare faith without an outward working of our faith, is to declare a dead faith. For our faith to be alive and growing, we must act on it.
