Just as there is no one-sided coin, there is no one-sided walk of faith. Each aspect of our walk with Him is sovereignly decreed - the smooth, the rough and all that is in-between.
The real crisis for Tiger Woods is not salvaging his marriage and career (though his marriage is immensely important.) The real crisis for him is the condition of his soul. A soul without the forgiveness of Jesus Christ will face eternal damnation and separation from God. Tiger Woods, just like all of us, needs a foreign rightousness that is outside of himself - an extraneous rightousness imputed to him by God through Christ.
This is the most important advise you can ever give a sinner. Brit Hume or any other Christian will pay a price for daring to do so. Tiger Woods will pay an infinitely higher price if he rejects it. This is no doubt the most important piece of unsolicited advise he will ever hear.
I pray that Tiger accepts it.
