“Don’t worry.” When you’re worried, it’s about the single most frustrating thing someone can say, isn’t it? With two words, they’ve just demanded the impossible. Except... we really don't have to worry. Jesus has it all under control.
As believers, we have the Holy Spirit within us as our guide to help us discern right from wrong and help us resist temptation. It may be a difficult choice, but it is a matter of choice to give in to temptation and sin, or to stand strong in our faith and resist.
