'Doubts' in the Bible

But he must ask in faith, without any doubts, for the one who has doubts is like a wave of the sea that is driven and tossed by the wind.

But the wisdom from above is first pure [morally and spiritually undefiled], then peace-loving [courteous, considerate], gentle, reasonable [and willing to listen], full of compassion and good fruits. It is unwavering, without [self-righteous] hypocrisy [and self-serving guile].
