I am of mixed minds about this.
There is a subtle difference between honoring God because He made you a person of faith who can win, and honoring God because He made you win.
The former group of people are expressing gratitude for being put on the “path” of righteousness.
The latter group are putting God in the same category as luck.
And casinos are full of people quietly praying that “God” will help them win their next gambling game. And this is a real definition of “Taking God’s Name in vain.”
Perhaps this distinction isn’t so subtle after all.
When you pull off a major success in your profession, do you recognize God's hand in it, and render Him praise and gratitude for the talents he blessed you with, the timing, the idea, etc. that made it all possible?
IMHO, that's all these people are doing.
Did not Paul make references to sports in his letters, when speaking about the glory of God?
