Righteousness is something we are called to pursue but lust is something we are called to stay away from.
Sometimes it seems as though leading a sexually pure life (not viewing porn and being engaged in solo-sex, not experimenting on sex and getting lost in the lust of this world) is something given to a few as a gift from God. But the Bible says, those who runaway from sexual immorality will stay away from it; and those who purse sexual purity will find it.
