James 1:7 - Albert Barnes' Notes on the Bible

For let not that man think that he shall receive anything of the Lord - Compare Hebrews 11:6. A man can hope for favor from God only as he puts confidence in him. He sees the heart; and if he sees that there is no belief in his existence, or his perfections - no real trust in him - no reliance on his promises, his wisdom, his grace - it cannot be proper that he should grant an answer to our petitions. That will account sufficiently for the fact that there are so many prayers unanswered; that we so frequently go to the throne of grace, and are sent empty away. A man that goes to God in such a state of mind, should not expect to receive any favor.
