ABEL'S SACRIFICE OF SELF
Not even when Abel and Cain were making the first sacrifice – not even then did God pay attention to their gifts. He looked into their hearts, and the gift that was acceptable was the one offered by the one who was acceptable in his heart. Abel, peaceable and righteous in sacrificing in innocence to God, taught the rest of us that when we bring our gift to the altar we should come, like him, with the fear of God, with a heart free of deceit, with the law of righteousness, with the peace of concord. He sacrificed in such a way, and so he was worthy to become, afterwards, himself a sacrifice to God: he who bore witness through the first martyrdom, who initiated the Lord’s passion by the glory of his blood, had both the Lord’s righteousness and the Lord’s peace. Such are those who are crowned by the Lord at the end; such are those who will sit and judge with him on the day of judgement.
