And whosoever shall compel thee to go a mile, go with him twain. Matthew 5:41
Our Lord’s teaching can be summed up in this: the relationship that He demands for us is an impossible one unless He has done a supernatural work in us. Jesus Christ demands that His disciple does not allow even the slightest trace of resentment in his heart when faced with tyranny and injustice. No amount of enthusiasm will ever stand up to the strain that Jesus Christ will put upon His servant. Only one thing will bear the strain, and that is a personal relationship with Jesus Christ Himself— a relationship that has been examined, purified, and tested until only one purpose remains and I can truly say, “I am here for God to send me where He will.” Everything else may become blurred, but this relationship with Jesus Christ must never be.
The Sermon on the Mount is not some unattainable goal; it is a statement of what will happen in me when Jesus Christ has changed my nature by putting His own nature in me. Jesus Christ is the only One who can fulfill the Sermon on the Mount. Oswald Chambers, My Utmost for His Highest
