Ah, yes, but even the dogs eat the crumbs that fall from the Master's table. Often we talk about faith in terms of submission, acceptance, acquiescence, and there are some realities we can neither change nor control. Sometimes faith must accept what is and deal with it as best we can. There are other times, however, when God expects more of us. Prayers of resignation are not the only prayers that belong to faith.
Expectation is a blood relative of hope and faith.
And her persistence was both encouraged and extolled. That is also the Biblical witness. I think of Jacob who wrestled all night with God and would not let go until he received a blessing. I think of the strange parable of Jesus of the importune widow who unmercifully nags a judge until he relents, and she is praised for her persistence. Do we really want it, can we taste it, for then and perhaps only then, shall we be satisfied.
