A soft tongue

Proverbs 25:15

With patience a ruler may be persuaded

and a soft tongue will break a bone.

What an encouragement this verse is in times of disappointment like these.
Looking back at this verse, I thought of 2 other passages in the New Testament that relates to it:

Luke 18:1-8 

 Then he told them a parable about the need to pray continually and never lose heart.'There was a judge in a certain town,' he said, 'who had neither fear of God nor respect for anyone. In the same town there was also a widow who kept on coming to him and saying, "I want justice from you against my enemy! For a long time he refused, but at last he said to himself, "Even though I have neither fear of God nor respect for any human person, I must give this widow her just rights since she keeps pestering me, or she will come and slap me in the face." And the Lord said, 'You notice what the unjust judge has to say. Now, will not God see justice done to his elect if they keep calling to him day and night even though he still delays to help them? I promise you, he will see justice done to them, and done speedily. But when the Son of man comes, will he find any faith on earth?'

2 Timothy 2:24-26 

 ...and a servant of the Lord must not engage in quarrels, but must be kind to everyone, a good teacher, and patient. He must be gentle when he corrects people who oppose him, in the hope that God may give them a change of mind so that they recognise the truth and come to their senses, escaping the trap of the devil who made them his captives and subjected them to his will.
