Theophylact of Bulgaria
The Apostle said much in praise of Abraham, and someone might object: What is this to us? Therefore he states that this was written for us also. Faith will be accounted to us also as righteousness, if only we possess it, believing in Him who raised Jesus. If you doubt how you can be justified, then set before your soul Jesus, who blotted out all your sins. He died not for His own sin, but for the sin of the world. Since He died without having sin, He rightly rose. For how could He who had no sin be held in Hades? Therefore He died and rose for this purpose: to free us from sins and to make us righteous. As Abraham believed that his body, already deadened, would become fruitful, so you too must believe that Jesus died and rose. Then it will be accounted to you as righteousness, as it was to your forefather Abraham.
