“Man does not live on bread alone, but on every word that comes from the mouth of God.” (Matthew 4:4)

After fasting for 40 days and nights, the temptation for Jesus to turn stone into bread must have been even stronger and more realistic than his hunger during the fast.  At that moment, He only had God's word to rely on to resist the temptation.

“Man does not live on bread alone, but on every word that comes from the mouth of God” comes from Deuteronomy Chapter 8 Verse 3. 

Jesus uses this passage to remind us that He is the Road, the Truth and the Life.

No one can be immune from temptation.  However, in “The Lord’s Prayer”, Jesus teaches us to pray this way, “'Lead us not into temptation.” 

The reason why we succumb to temptation is because we do not pray enough or we do not pray with our hearts.

Actually, when we take the initiative to fast, our will to resist temptation is strengthened.  As Jesus once said, “Some evil spirits can only come out by prayers and fasting”.
When we regularly study the Bible and receive Holy Communion, our thoughts and minds naturally turn away from sin.
