To know that Jesus on this earth was tempted just like
we are tempted! He was able in all his humanness to resist that
temptation with the Holy Spirit. He was fully God and Man on the earth, but in all his humanness he was able to resist because he relied on the Holy Spirit.  He never sinned! 

If we KNOW HIM we too can resist any
temptation that comes across our path!  Unlike Christ we are sinners and have fallen.  However we can resist because we have the Holy Spirit. 

Every circumstance that comes our way….. we have a CHOICE to either Glorify God or not.
