Verses and fathers Sayings
“But when a righteous man turns away from his righteousness and commits iniquity, and does according to all the abominations that the wicked man does, shall he live? All the righteousness which he has done shall not be remembered; because of the unfaithfulness of which he is guilty and the sin which he has committed, because of them he shall die.
"'If the righteous turns away and commits iniquity, I will not remember the righteousness which he did before; in his sin he shall die.' Learn, then, brother, that it is not he who begins well who is perfect. It is he who ends well who is approved in God's sight. Give then no sleep to your eyes or slumber to your eyelids that you may be delivered as a roe from the net and a bird from the snare'. For, behold, you are passing through the midst of snares; you are treading on the top of a high wall whence a fall is perilous to the faller; wherefore do not immediately attempt extreme discipline; above all things beware of confidence in yourself, lest you fall from a height of discipline through want of training."
--St. Basil the Great
