Blessed are they that have not seen and yet have believed.
Faith is kind of like navigating a row boat.
In a row boat the rower faces the opposite way he is heading. He rows with his back toward the destination. So it is with our faith in spiritual matters. We do not see or touch forgiveness as we might see or touch an object. Rather, we trust that forgiveness is real and that the God who has shown himself to be loving toward us, is in fact a God of love.
