Learning (again) to Pray

I'm reading "A Woman's Call to Prayer" by Elizabeth George. Great reminders. Great book. I loved a quote by D.L. Moody that she included:
`
Prayer is the bow,
the promise is the arrow:
faith is the hand which draws the bow, and
sends the arrow with the heart's message to heaven.
The bow without the arrow is of no use; and
the arrow without the bow is of little worth; and
both, without the strength of the hand, to no
purpose.
Neither the promise without prayer,
nor prayer without the promise,
nor both without faith,
avail the Christian anything.
What was said of the Israelites, "They could not enter in,
because of unbelief,"
the same may be said of many of our prayers: they
cannot enter heaven, because they are not put up in
faith.
`
Lord, help me to offer prayers that avail much and help me in my unbelief to fully accept and embrace that power of your healing. I love You. I trust You. Amen.
