On Tim Challies' blog today he had a link to an article entitled "43 Quotes About Prayer To Inspire Your Prayer Life." I couldn't copy the entire article but I found four quotes that rang true to me.
1.”Our prayers may be awkward. Our attempts may be feeble. But since the power of prayer is in the one who hears it and not in the one who says it, our prayers do make a difference.” – Max Lucado
2. “To be a Christian without prayer is no more possible than to be alive without breathing.” – Martin Luther
39. “As it is the business of tailors to make clothes, and the business of cobblers to mend shoes, so it is the business of Christians to pray!” – Martin Luther
40. “Prayer is not overcoming God’s reluctance, but laying hold of His willingness.” – Martin Luther
