'Doubt' in the Bible

Immediately Jesus reached out His hand, caught hold of him, and said to him, “You of little faith, why did you doubt?”

Jesus answered them, “I assure you: If you have faith and do not doubt, you will not only do what was done to the fig tree, but even if you tell this mountain, ‘Be lifted up and thrown into the sea,’ it will be done.

I assure you: If anyone says to this mountain, ‘Be lifted up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will happen, it will be done for him.

Then He said to them, “No doubt you will quote this proverb to Me: ‘Doctor, heal yourself. So all we’ve heard that took place in Capernaum, do here in Your hometown also.’”

Without a doubt, the inferior is blessed by the superior.

Have mercy on those who doubt;
