This is a true story:A son says to his father: 'Dad, would you be willing to run a marathon with me?'
The father, despite his age and his heart disease, says: 'YES'
So they run a marathon together.
The son asks: 'Dad, can you run another marathon with me?'
Again the father says: 'YES'
They run another marathon, together.
One day the son asks his father: 'Dad, would you please do The Iron Man with me?'
Now just in case you don't know, 'The Iron Man' is the toughest triathlon in existence; 4km swimming, then 180 km by bike, and finally another 42 km running, in one stroke.
Again his father says: 'YES'
Maybe this doesn't touch you by the heart yet.. until you see this video...
(put on sound!):

See how great is a love of a father for his son, as how great the love of our Lord Father in heaven is to us...
