The idea of obligation, tied in, obviously, with the idea of a commandment, is tough for Reform Jews. How can we declare that we are obligated to do anything when we undermine the commandedness of all mitzvot through or picking and choosing.

But when we use the term "picking and choosing" ( as we often do), we sell ourselves short. We are not pickers and choosers, but explorers and discoverers. When we try a commandment on an find that it fits or find that we want it to fit, we have made a discovery.

What have we discovered? We have discovered a true commandment and a true obligation. Not a universal commandments and obligations, but personal ones.

When I decided that going to services whenever one was available to me was good for me, it became a commandment and I became obligated to do go. We also sell ourselves short when we don't so things regularly. It betrays, to ourselves and others, how unserious we often are.

When there is perhaps a movie I am tempted to see or a concert I am tempted to go to (as is often the case), I must remember that I have entered into a state of obligation.

To clarify my previous comment, we become commanded and obligated when we choose to. But let us not think that these are commandments and obligations easily broken simply because we took then upon ourselves in a solitary act.
