'Wavering' in the Bible

But he must ask [for wisdom] in faith, without doubting [God’s willingness to help], for the one who doubts is like a billowing surge of the sea that is blown about 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].

Come close to God [with a contrite heart] and He will come close to you. Wash your hands, you sinners; and purify your [unfaithful] hearts, you double-minded [people].
