'Stumble' in the Bible
Jesus replied, Are [there] not twelve hours in the day? If anyone walks around in the daylight, he does not stumble, because he sees the light of this world.
Why that? Because [they did] not [pursue it] by faith, but as [if] by works. They stumbled over the {stone that causes people to stumble},
just as it is written, "Behold, I am laying in Zion {a stone that causes people to stumble}, and {a rock that causes them to fall}, and the one who believes in him will not be put to shame."
I say then, they did not stumble so that they fell, [did they]? May it never be! But by their trespass, salvation [has come] to the Gentiles, in order to provoke them [to jealousy].
For we all stumble [in] many [ways]. If anyone does not stumble in what he says, he [is] a perfect individual, able to hold in check his whole body also.
and "A stone of stumbling and a rock of offense," who stumble [because they] disobey the word to which also they were consigned.
Therefore, brothers, be zealous even more to make your calling and election secure, because [if you] do these [things], you will never ever stumble.
