Predestination at the Public School

Today my son came home from his first day back to school. As part of his mandatory curriculum, he will take band (i.e. music) class. One of the features of this class is professional musicians (or, at least professional musical instrument salespersons) will come in and "fit" him to the instrument that best matches his physical characteristics. Apparently there is a whole science behind matching person and instruments (not being musically inclined, I have no way of verifying the truth of this presupposition). I suppose this means kids with fat, short fingers won't be allowed to play piano, and kids with small lung capacity will be steered away from the flute.

As my wife was trying to explain this to me, I couldn't help thinking the following:

As humans we have no problem believing that we are "predestined" to best fit certain types of instruments, but as Christians so many refuse to believe that we are predestined in regards to our salvation.

For crying out loud, we blindly accept the fact that little Johnnie can't play the trumpet and "must" play the triangle because his physical characteristics determine it, but we refuse to believe that God determines anything regarding our relationship to him. Seems a bit inconsistent to me.
