Every time we turn to Christ in faith it is like a moment of Sabbath, a little foretaste of eternal rest and glory. The gift of that moment lies not in what we do but what we receive. It is the holy time set aside to receive the greatest gift of God ever has to give, which is himself, in his own beloved Son.
We cultivate our feelings the way we cultivate a garden: we can't entirely prevent weeds from coming up, but we can take care to remove them before they do much harm.
