Christ’s summary of the parable teaches a moral lesson, prompted by Peter’s question. Self-examination is so important, and there must be a readiness to forgive in all true believers.
He was delivered to the tormentors, the scourgers. ‘So likewise shall my heavenly Father do also unto you’ – these words come from the man of love. He taught that there is eternal punishment for all who die unreconciled to their God. If you have never been amazed that God should come from heaven and been astonished at the readiness of God to forgive just on the asking as long as we are sincere, then the gospel has never really touched your heart. You must come to him. You cannot spurn and ignore him. It is such a tragic thing to do. You need his love, and may have it if the Spirit works in your heart and you long for a new life. You can walk with him. You must come to Jesus Christ.
In this parable, given first to Peter and the disciples, we see that it is appropriate for warnings to be given even to true believers. They are the very means that Christ uses to turn us back from paths that would be destructive to us. They bring reproof and correction which keep us from fatal error. The believer can never lose his salvation for Christ keeps him, but at times the way he keeps him is by showing him real dangers that he must avoid.
