He made us one with him when he chose to be tempted by Satan. We have heard in the gospel how the Lord Jesus Christ was tempted by the devil in the wilderness. Certainly Christ was tempted by the devil. In Christ you were tempted, for Christ received his flesh from your nature, but by his own power gained salvation for you; he suffered death in your nature, but by his own power gained glory for you; therefore, he suffered temptation in your nature, but by his own power gained victory for you.
If in Christ we have been tempted, in him we overcome the devil. Do you think only of Christ’s temptations and fail to think of his victory? See yourself as tempted in him, and see yourself as victorious in him. He could have kept the devil from himself; but if he were not tempted he could not teach you how to triumph over temptation.
-- Saint Augustine of Hippo
