How does the faith of Abraham and Rahab illustrate the concept of justification?

The faith of Abraham and Rahab serves as prime examples of how justified faith is demonstrated through actions. Abraham showed his faith through his willingness to offer Isaac, signifying that genuine faith results in obedience to God. Rahab, despite her sinful past, acted on her belief by hiding the spies, showing that faith brings forth actions reflective of one's trust in God. Their works served as proof of their faith to the world, not a means to their justification before God, which is entirely through Christ. This distinction is crucial for understanding the relationship between faith and works in the life of a believer.
