Three times had Peter denied his Master; three times, then, did the Lord challenge his love. This was according to "righteousness." But in thus challenging Peter, the Lord gave him the opportunity of now thrice confessing Him. This was according to "grace." In His first question the Lord challenged the superiority of Peter’s love. In His second question the Lord challenged whether Peter had any love at all. Here, in His third question the Lord now challenges even his affection! Most searching was this! But it had the desired effect. The Lord wounds only that He may heal.
