Soccer: God would not choose soccer because it is rowdy and it gave birth to Hooligans. Those people who fight and throw chairs after the end of every game.
Boxing: God will always win if he was to participate but he doesn't like violence so that is never going to happen.
Wrestling: That is fighting and hurting people. It is also about drug use and destroying your body. God will not sanction wrestling as a sport.
Car Racing: Car racing is a dangerous sport and God will not approve of people putting their lives in danger because of the thrill. He will not participate because he wouldn't need a car in the first place. God will already be at the finish line before the rest of the contestants' even start their engine. Where is the fun in that? As you can see car racing will not be the favorite sport of God.
Athletics relay: God wouldn't need the help of others to complete a relay. He'll go all the way and will be first. This sport would make sense.
Weight lifting: This will be too easy. God would lift everything with one finger. Where is the fun in that?
Running: God doesn't run. He is not afraid of anyone. He is neither in a hurry so what is the point?
Golf: Adultery, Bootyism, if you don't know what that is, search for "what is bootyism". Tiger Woods, Nick Faldo and there are more. That is in the thou shall not list of the 10 commandments.
Ice Hockey: You must be Canadian or American to understand this. As God isn't from any of those countries he wouldn't understand why you would leave the game and beat the heck out of your opponent. It is like boxing and wrestling combined on ice. God wouldn't be picking this one.
Darts: God will say that Darts is not a sport. How can you have beer on one hand and darts on the other and call that sport? You don't practice sport in a pub.
Walking : You might be thinking walking is not a sport but it is. It is easy and all you have to do is put one foot in front of the other and that is all. How do we know that God will participate in this sport? Here is what the bible has to say.
Gen 6:9 "This is the account of Noah. Noah was a righteous man, blameless among the people of his time, and he walked with God".
As you can see from what the bible says. If you want to participate in a sport that God likes, you should start walking.
