'Doubt' in the Bible

Immediately Jesus extended His hand and caught him, saying to him, “O you of little faith, why did you doubt?”

Jesus replied to them, “I assure you and most solemnly say to you, if you have faith [personal trust and confidence in Me] and do not doubt or allow yourself to be drawn in two directions, you will not only do what was done to the fig tree, but even if you say to this mountain, ‘Be taken up and thrown into the sea,’ it will happen [if God wills it].

But so that you may know that the Son of Man has the authority and power on earth to forgive sins”—He said to the paralyzed man,

I assure you and most solemnly say to you, whoever says to this mountain, ‘Be lifted up and thrown into the sea!’ and does not doubt in his heart [in God’s unlimited power], but believes that what he says is going to take place, it will be done for him [in accordance with God’s will].

Therefore let all the house of Israel recognize beyond all doubt that God has made Him both Lord and Christ (Messiah, Anointed)—this Jesus whom you crucified.”

Get up, go downstairs and go with them without hesitating or doubting, because I have sent them Myself.”

For I am convinced [and continue to be convinced—beyond any doubt] that neither death, nor life, nor angels, nor principalities, nor things present and threatening, nor things to come, nor powers,

Therefore I want the men in every place to pray, lifting up holy hands, without anger and disputing or quarreling or doubt [in their mind].

In the same way God, in His desire to show to the heirs of the promise the unchangeable nature of His purpose, intervened and guaranteed it with an oath,

And have mercy on some, who are doubting;
