In Christopher Marlowe's The Tragical History of Doctor Faustus, Faustus began to believe that human salvation was impossible because he read the scripture and saw that all human beings sin and are doomed. He thought that this meant that no matter how you lived your life, and how much you tried to be a good person, in the end you would still sin and thus God won't forgive you. This is why he consciously gave in to sin. 

In addition, he had been misled by Mephastophills, who caused him to misread the scriptures. Mephastophills is the Devil, and obviously the Devil won't tell the truth because he wants to collect more souls to torture in his realm. Faustus fell for his tricks and was mislead to misinterpret the scriptures, which lead to him losing his soul ultimately.
