James says the person who doubts when asking God is like what?

Answer: A wave of the sea

He who doubts is like a wave of the sea, blown and tossed by the wind — a double-minded man, unstable in all his ways.

“But he must ask in faith, without doubting, because he who doubts is like a wave of the sea, blown and tossed by the wind. That man should not expect to receive anything from the Lord. He is a double-minded man, unstable in all his ways.”— James 1:6-8 (BSB)
