Wherever we turn to, there are Godly reminders about the work of Christ on the cross. Although, with the internet and co we can still do what the word says:

Set your affection on things above, not on things on the earth… mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence and covetousness which is idolatry; Col 3:2, 5.

The best way to keep sin at a distance is to make sure Jesus stands between you and temptation (Joe Stowell).
