28 Have thou not known? Have thou not heard? The everlasting God, LORD, the Creator of the ends of the earth, faints not, nor is weary. There is no searching of his understanding.
Bible verses about "doubting" | ACV
31 Be not therefore anxious, saying, What may we eat? or, What may we drink? or, What may we wear? 32 For the Gentiles seek after all these things, for your heavenly Father knows that ye need all these things. 33 But seek ye first the kingdom of God and his righteousness, and all these things will be added to you. 34 Be not therefore anxious for the morrow, for the morrow will be anxious about things of itself. Sufficient for the day is the evil of it.
6 But let him ask in faith, doubting nothing, for he who doubts is like a wave of the sea driven by wind and tossed about.
