Why is Abraham considered our “father of faith” when so much of his biblical biography shows examples of his utter lack of faith? He laughed in God’s face about a son from a barren wife, circumvented God’s prophesy for that son and lied to two different kings about his relationship with Sarah, putting her in real danger.
In the Torah parashah (portion) called Vayera (“He appeared,” Gen. 18:1–22:24), we learn that despite Abraham’s (and Sarah’s) ups and downs, their faith was growing, not shrinking. That is why God Himself not only credited Abraham’s trust as righteousness but also made them patriarch and matriarch of “a great and mighty nation” through which all nations of Earth would be blessed.
