WHEN YOU ARE TEMPTED TO SIN, QUOTE SCRIPTURE. JESUS DID.

"1Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil. 2And when he had fasted forty days and forty nights, he was afterward an hungred. 3And when the tempter came to him, he said, If thou be the Son of God, command that these stones be made bread. 4But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God." (Matthew 4:1-4, The Holy Bible, King James Version)
