How strong is your faith? Can ones own faith ever be strong enough?

In this passage we have a man who Jesus asks directly “Do you believe?”. The man answers yes, but not enough, he asks Jesus for help to believe more, to believe stronger.  Maybe it is easy for us today, 2000 years after this event took place to say: “How could someone talking face-to-face with Jesus not have an incredibly strong belief?”.  The reverse question could also be asked of us: “How could we who both read this story in Sacred Scripture and receive Jesus in the Sacrament of Holy Communion, not have an incredibly strong belief?”.  Perhaps the answer is hidden somewhere in our fallen human nature, so we need to pray and ask the Lord: “Jesus, help my unbelief!”.
