'Fall' in the Bible

Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall:

and saying, 'Where is the promise of his presence? for since the fathers did fall asleep, all things so remain from the beginning of the creation;'

Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.
