What does the Bible say about Abraham's faith in trials?

In Genesis 12, Abraham's faith is put to the test as he encounters a grievous famine in the land of Canaan, a place promised to him by God. Instead of returning to his former home, he chooses to go to Egypt, demonstrating a pivotal moment in his faith journey where he must rely on God's provision. This episode illustrates how faith can be challenged in dire circumstances, as Abraham, despite being known for his faith, succumbs to doubt and fear when it comes to the safety of his wife, Sarah. His decision to refer to her as his sister reflects a temporary lapse in his trust in God’s care.
