Many have erroneously assumed that the disciples readily accepted Christ’s teachings concerning His death, burial, and resurrection. When Simon Peter first heard the Lord teach on the subject, he immediately took the Lord and rebuked Him for what He said. The Lord Jesus responded by rebuking Peter, going so far as calling him Satan. Peter rebuked the Lord because the Lord’s teaching did not align with Peter’s perception and plans. He had no authority for rebuking the Lord and should have submitted himself to the Lord’s teaching. Some things have changed, but some have not. Believers today “rebuke” the Lord when they respond carnally to God’s working within their lives. They fail to realize their duty is to submit to the Lord.
God's children are supposed to be easily recognizable through their love one for another (John 13:35). Today's passage teaches Christians to be both kind and forgiving. In the midst of these two exemplary qualities, the Lord desires His children to show forth a tender heart. This means that our hearts ought to be easily moved when other believers are experiencing either joy or distress in their lives (Romans 12:15). Unfortunately, instead of exemplifying a tender heart, far too many believers are becoming more like the world by displaying a divisive spirit and by devouring one another (Galatians 5:15). Believers who are hard-hearted toward others are generally hard-hearted toward the Lord as well (1 John 3:17).
