So much bad theology in this thread.
I'm a Christian philosopher and I believe that God is certainly NOT directly helping Tebow win a game. If God is helping him win in any way it is because He blessed him with natural talent and athleticism, and Tebow, in his devotion, has worked hard to develop those talents and use them to the glory of God. God is not directing passes or causing fumbles, or anything of that sort.
However, the notion that humans can't glorify God and such is blasphemous is quite wrong. We can't add to God's infinite glory, but our purpose in creation is to worship and glorify God. Tebow tries to do that by honoring his Lord with his football skills. There is nothing blasphemous about that.
On the point of African people starving: Most extreme famine and starvation is the fault of poor and corrupt governments who withhold proper care and supply to their people. Notably, the atheistic communist gov't of Mao Zedong in China purposely starved over 100 million of its own people in the name of its godless political agenda.
The point is this: Much suffering is the cause of the willful rebellion of free moral agents, and often the sins of people cause great suffering and destruction for others, sometimes thousands and millions of others.
The Christian believes it is our duty to alleviate suffering and help the less fortunate, but such evils will not be fully alleviated without the changing of hearts by the Gospel or until the physical world will be remade at Christ's return.
In the case of Clarke and the sickle cell anemia: Christians hold that natural evil is either an effect of the Fall and sin of Adam or is an instrumental good which is used to bring glory to God in some way. Or it may be both.
In conclusion, God is not directly helping Tebow, but is indirectly through His gift of natural talent coupled with Tebow's devotion in developing them. I don't think God actively wills Tebow to victory, but such is an effect of God's permissive (chance, choices of free agents) rather than His decretive will.
