Though we could speak of doing the impossible, I think it’s better to speak of becoming what we once thought was impossible. The emphasis should always be on becoming over doing. At one point in his life Abraham thought it was impossible for him to become a father—it was so impossible that he laughed at the thought of it. But through faith that’s exactly what he became. The seed of faith grew in Abraham’s life until one day he became what he had previously assumed was impossible.
