Triathlon is a beautiful metaphor for life.  Three in one... and the one isn't complete unless you can function well on all disciplines.  Just like triathlon you exist three in one... Body, Mind, Spirit.  This is also the best explanation of the trinity.  We are made in the image of God, and He too exists three in one... Father, Spirit, Son.  And just like triathlon, to be able to function properly without injuring yourself or others, you must be able to listen.  In triathlon you have to listen to your body and know when to quit so you prevent injury.  That's why there is a rule in triathlon that you are not allowed to wear ear buds or listen to music.  If you're not paying attention to your surroundings, you're going to get hit or hit someone else.  In life, you must listen to the spirit of God.  He is always speaking, there are just certain factors that keep us from hearing him.  Unforgiveness, past wounds, wrong believing, these are all things that will keep you from hearing him.  When you do hear Him, it changes your life forever, you step into the kingdom, and you become who you are and were always meant to be.  Old patterns are broken and you start living in a manner that no longer hurts yourself or others.  This is the gospel... hope for a renewed life... and it only comes through Jesus.
