We have no rights. We're all beggars at God's table. A little humility and honesty demands that we begin there. There is risk in faith. We have to come to Jesus even at the risk of being disappointed.
Faith is risky.
She would have stayed home, if she had reasoned it all out and determined that God was not her god - that the journey was pointless. She would have risked nothing, and gained nothing. She would have remained as she was - hopeless and alone. There is always the possibility of failure or disappointment. So we hold back.
