'Wavering' in the Bible

But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed.

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].
