4Let perseverance finish its work so that you may be mature and complete, not lacking anything. 5If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you. 6But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind. 7That person should not expect to receive anything from the Lord.
8Such a person is double-minded and unstable in all they do.
