All faith must have an action that corresponds to it. When Abraham took a step of faith, he acted the way he expected it to happen, and his faith co-operated and brought it to pass. Faith must co-operate with actions, and by actions faith is perfected. No, you can only talk about it. You cannot demonstrate your faith unless you can show an action that has proved your faith.
Faith is a mental capacity, and an action is in the material world.
The example of Abraham James gives the example of Abraham, whom God told to offer his son on the altar, which would have delayed the fulfillment of the original promise of an extended family. Abraham and his son journeyed with his servants to the foot of the mountain. No, he had faith with corresponding actions. He went up the mountain without an offering, not knowing how it would work out. Yet he did what God had told him.
