The words of the Lord Jesus in the Sermon on the Mount found in Matthew 7:1-5 are heavy and soul-searching, but they also require a great deal of thought and consideration if they are to be put into practise. These words have been misunderstood over time and probably also badly applied, but this does not excuse us from tackling both their implications and their correct application – which again (like so much in the Sermon on the Mount) is a matter of the heart.
