Have been studying prayer for adult Sunday School, ran across this quote in Leith Anderson's book, "Praying to the God You Can Trust":
"Some Christians mistakenly think that the Bible's call for faith means believing God will answer a prayer precisely as it is requested. Faith isn't faith in an answer. It isn't faith in prayer. It is faith in God."
We need to be aware that God answers prayers as He sees fit - not on the basis of how much "faith" we can work up in the answer we want.
By the way, this little book has been excellent so far, particularly the section on how God answers contradictory prayers.
