Like all thoughts, evil thoughts come from the heart, and there, our hearts can turn deceitful.  It's a good gift to lust for your man/woman, however, like any good gift Satan is quick to turn it into something pervert that God did not intend for our own destiny.  Because unrestrained lust leads to a general chaos.  Satan is also the bombardement of the media which pollutes the idea of God, most especially trough pornography and also constant subtle wrong messages. 

We can all be victims.  If we fall, rather than excuse ourselves we must seek to be embraced by Jesus from repenting.  Wrong lust damns us, so we must flee with determination from it and break free.  If we ask, Jesus will help us instead to look with love, with purity; THAT'S HOW JESUS LOOKS.   

Each one of us who recognize Him as our Lord, has a primary calling; that is to be the light and salt to the world.

In what ways?  God asks from us to do our role heartily, as to the Lord more than to the man (for showing off).  As we try to navigate in troubled waters, one sure way to keep away from the Christian challenges is to isolate, a direction taken in the extreme by those who join monastic life.  Such an approach may indeed keep us seperated from the messy world around us.  But our isolation will rob others of the witness of a Spirit-filled follower of Jesus.  Wouldn't that be selfish?  Jesus modeled and instructed an approach that didn't isolate.  In John 17:15 Jesus prayed for His disciples to the Holy Father: "I do not pray that you take them out of the world, but that you keep them from the evil one".  There He instructed His followers to be the salt of the earth.  Salt has cleansing, flavouring and preservative qualities, but does no good if it is confined to a box. 

Therefore let us be the bearers of light to those who  are in need of such a light in their lives.  And seek no merit from man but only from God, out of the love for Him; after all it's the light of God that flows trough you to others, and it's not for you to keep.
