Throughout the books Augustine faces many burdensome temptations. He battles with the temptations of all five of the senses. He is in love with beauty in all the fallacious ways. Even from the beginning in book I and II we learn that sin will tempt Augustine. (Augustine, II) We learn that sin will tempt us in any and every situation. Augustine's first sinful experience happens in book II when he steals from a pear tree. Augustine says he has no "desire to enjoy the things I stole, but only the stealing of them and the sin." (Augustine, II.5) He finds pleasure in doing forbidden things. Satan simply took over parts of Augustine's life and this was a moment when Augustine let Satan control him. He "falls away from God to become a negative reflection of omnipotence." (Vaught, 21) His soul desired the sin. His pear-stealing episode pointed out his need for redemption. (Vaught, 54) While Augustine is studying at Carthage his sinful nature takes over again. He continued to push his faith and push God away and instead had the longing for lust. His love for stealing turns into a love of loving. He was desiring love and to be loved so abundantly. Augustine "did fall in love, simply from wanting to." (Augustine, III.2) As he continues to move away from God, he continues to remain empty. Augustine becomes a slave to lust and soon finds joy in his sexual addictions. (Augustine, VI.4) He should be longing for God's love rather than the love given from women. He never found full fulfillment in either of these sins and he later realizes that he will only be fulfilled when he seeks God and finds rest in Him. (Vaught, 69) .
