As he readies the universe for eventual rule by the Father forever, when he comes the Son will prioritise the elimination of all causes of sin. Temptations of Satan. Temptations of technology, drugs, idols, immoral professions, weaponry, glamour, and everything else which has potential to cause sin. Sin will become a rarity. He knows how to do it effectively and decisively. He has lived in weakness like us, with these temptations all around. He knows.
