You don't understand. You can have riches. You just can't be obsessed with them to the point where they are the #1 focus of your life.
There are a lot of professional athletes that are Christians with enormous wealth but they always give credit to God first and foremost.
This is called SPIN. It isn't at all what the bible actually says. Taken 'in context' it says quite clearly that you must sell all of your possessions and follow Jesus, that it is basically impossible for a rich man to "enter into the kingdom of heaven". Again, taking "into context" the fact that YOU are commanded to be "Christlike" (which means to mimic Jesus and his example here on earth), then you are not supposed to have 'a place to lay your head', that you should not be 'storing up your treasures on earth' (aka - no savings, no investment - only what 'the Lord' provides today).
This is just another example, in the long line of examples, of how you (like most Christians) cherry-pick the bible passages that you want
it to be saying and ignore (or SPIN) the others to fit the context that you want. It's called inventing your own version of Christianity to suit your desires. And rich professional athletes are no exception. They are storing up treasures here on earth (as are you if you have a bank account, a house, a computer, or other common conveniences).
Sorry, by the words of your own 'master' you are not a true follower of that master.
