The operative part of the prayer is '...but not yet!' He knows what he has to do ultimately, but it's just that he is not ready for it yet. This is a universal dilemma that all of us face at various stages in our lives. We keep procrastinating on charity, for example, till, we tell ourselves, our own nest egg is just right. But the 'not yet' keeps on shifting the goalpost, we step back from the crease, and the good deed just never happens.
