The letter to the Hebrews draws a strong connection
between the cross and prayer. Because every moment of our
earthly existence is threatened by death, and we know neither the
day nor the hour when that existence will come to an end, we,
too, need to cry out to the God who can save us. Like Moses, we
need the help of our fellow Christians to hold up our arms when
they grow tired. We, too, need the help of the Holy Spirit to
make up for what is lacking in our prayer.
