Rather than always fighting temptation, consider fleeing from it. Distance yourself from any point of vulnerability. Why would you battle a temptation in the future if you have the power to eliminate it today?

"No temptation has overtaken you except what is common to mankind. And God is faithful; he will not let you be tempted beyond what you can bear. But when you tempted, he will also provide a way out so that you can endure it." 1 Corinthians 10:13
