In the Jewish prayer book, there are a great number of blessings.
Many of them concern simple, mundane activities, such as opening one’s eyes in the morning, stretching, standing on one’s feet, walking, and so on.
Why must we say them every day?
Because the significance and wondrousness of our ability to do these things tends to get lost.
We rarely recognize them as gifts from God until they are suddenly gone.
It is only when pain prevents us from walking with ease that we recognize and acknowledge God’s role in “firming our footsteps.”
–Rabbi Adin Steinsaltz
