Hebrews 2:18 (NIV)

18 Because he himself suffered when he was tempted, he is able to help those who are being tempted.

Explained: 
Because He has gone through temptation, He is able to help us when we are tempted.  

Jesus did not come into this world to gain status or political power, but to suffer and die so that we could have eternal life. Through the Lord’s suffering God made Him fit to bring man unto salvation.
